  • Mobility Enhancement of Strained Si Transistors by Transfer Printing on Plastic Substrates
    OPEN NPG Asia Materials (2016) 8, e256; doi:10.1038/am.2016.31 www.nature.com/am ORIGINAL ARTICLE Mobility enhancement of strained Si transistors by transfer printing on plastic substrates Wonho Lee1, Yun Hwangbo2, Jae-Hyun Kim2 and Jong-Hyun Ahn1 Strain engineering has been utilized to overcome the limitation of geometric scaling in Si-based thin-film transistor (TFT) technology by significantly improving carrier mobility. However, current strain engineering methods have several drawbacks: they generate atomic defects in the interface between Si and strain inducers, they involve high-cost epitaxial depositions and they are difficult to apply to flexible electronics with plastic substrates. Here, we report the formation of a strained Si membrane with oxidation-induced residual strain by releasing a host Si substrate of a silicon-on-insulator (SOI) wafer. The construction of the suspended Si/SiO2 structures induces 40.5% tensile strain on the top Si membrane. The fabricated TFTs with strained Si channels are transferred onto plastics using a roll-based transfer technique, and they exhibit a mobility enhancement factor of 1.2–1.4 compared with an unstrained Si TFT.

For 32 and 22nm nodes, intense research work focuses on the integration and optimisation of these different techniques by cumulating the effects of different stressors. To estimate the level and the distribution of the stress field generated in the transistor channel by such multiple processing steps is a complex issue.

    NANO & GIGA CHALLENGES 2007 12-16 MARCH TEMPE, AZ ARIZONA STATE UNIVERSITY NANO & GIGA CHALLENGES 2007 will provide a forum for academics, students, industrial researches, investors and business development professionals from around the world to discuss cutting-edge nanotechnology as it relates to advanced silicon based micro- and optoelectronics. CMOS technology has sustained exponential progress (Moore's Law) for four decades. However, scientists and engineers agree that this progress will run into what is called the red brick wall of technical and economic limitations some time during the next decade. The use of nanotechnology is vital to the development of future electronics and photonics.

    Monash Centre for Electron Microscopy 10th Anniversary Lecture Professor Sir Colin Humphreys CBE FREng FRS Chair: Dr Alan Finkel AO FAA FTSE Thursday 22 November 2018 Lecture Theatre G81 Learning and Teaching Building 5.30pm 19 Ancora Imparo Way Clayton Campus How electron microscopy can help to save energy, save lives, create jobs and improve our health Electron microscopes can not only image single atoms, they can identify what the atom is and even determine how it is bonded to other atoms. This talk will give some case studies from Colin Humphreys’ research group going from basic science through to commercial applications, featuring two of the most important new materials: gallium nitride and graphene. Electron microscopy has played a key role in the rapid advance of gallium nitride (GaN) LED lighting. LED lighting will soon become the dominant form of lighting worldwide, when it will save 10-15% of all electricity and up to 15% of carbon emissions from power stations. Electron microscopy has enabled us to understand the complex basic science of GaN LEDs, improve their efficiency and reduce their cost. The Humphreys’ group has been very involved in this. LEDs based on their patented research are being manufactured in the UK, creating 150 jobs. Next generation GaN LEDs will have major health benefits and future UV LEDs could save millions of lives through purifying water. Graphene has been hailed as the “wonder material”, stronger than steel, more conductive than copper, transparent and flexible. However, so far no graphene electronic devices have been manufactured because of the lack of good-quality large-area graphene.

In this work, we generate uniaxially strained silicon and anisotropically strained silicon germanium on insulator with strain in both ͗100͘ and ͗110͘ in-plane directions. The strain is uniform over fairly large areas, and relaxed silicon-germanium alloy buffers are not used. The magnitude of uniaxial strain generated by the process is very dependent on the in-plane crystal direction, and can be modeled accurately using the known mechanical properties of silicon and germanium. A maximum uniaxial silicon strain of 1.0% in the ͗100͘ direction is achieved. Numerical simulations of the dynamic strain generation process are used to identify process windows for achieving maximum uniaxial silicon strain for different structural geometries.

  • Graphene's 3D Nature
    Graphene's 3D Nature Contrary to what is believed, monolayer graphene (a sheet of carbon just one atomic layer thick) has 3D mechanical properties and they can now be properly measured and meaningfully described thanks to high-pressure Raman spectra measurements on the material. [47] The team has turned graphene oxide (GO) into a soft, moldable and kneadable play dough that can be shaped and reshaped into free-standing, three-dimensional structures. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz “could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates,” Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42] A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy. [41] All systems are go for launch in November of NASA's Global Ecosystem Dynamics Investigation (GEDI) mission, which will use high-resolution laser ranging to study Earth's forests and topography from the International Space Station (ISS).

  • Elastic Strain Engineering in Silicon and Silicon-Germanium Nanomembranes
    Elastic Strain Engineering in Silicon and Silicon-Germanium Nanomembranes By Deborah Marie Paskiewicz A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Materials Science) at the UNIVERSITY OF WISCONSIN-MADISON 2012 Date of final oral examination: 11/14/12 The dissertation is approved by the following members of the Final Oral Committee: Max G. Lagally, Professor, Materials Science and Engineering Mark A. Eriksson, Professor, Physics Thomas F. Kuech, Professor, Chemical and Biological Engineering Paul G. Evans, Associate Professor, Materials Science and Engineering Irena Knezevic, Associate Professor, Electrical and Computer Engineering ©Copyright by Deborah Marie Paskiewicz 2012 All Rights Reserved i Abstract Elastic Strain Engineering in Silicon and Silicon-Germanium Nanomembranes Deborah M. Paskiewicz Under the supervision of Professor Max G. Lagally At the University of Wisconsin-Madison Strain in crystalline materials alters the atomic symmetry, thereby changing materials properties. Controlling the strain (its magnitude, direction, extent, periodicity, symmetry, and nature) allows tunability of these new properties. Elastic strain engineering in crystalline nanomembranes (NMs) provides ways to induce and relax strain in thin sheets of single- crystalline materials without exposing the material to the formation of extended defects. I use strain engineering in NMs in two ways: (1) elastic strain sharing between multiple layers using the crystalline symmetry of the layers to induce unique strain distributions, and (2) complete elastic relaxation of single-crystalline alloy NMs. In both cases, NM strain engineering methods enable the introduction of unique strain profiles or strain relaxation in ways not compatible with conventional bulk processing, where strain destroys the long-range crystallinity.
