    Template for APEX (Jan. 2014) Controlled formation of high-mobility shallow electron gases in SrTiO3 single crystal Jung-Won Chang1, Joon Sung Lee1*, Tae Ho Lee1, Jinhee Kim2, and Yong-Joo Doh1* 1Department of Applied Physics, Korea University Sejong Campus, Sejong 339-700, Republic of Korea 2Korea Research Institute of Standards and Science, Daejeon 305-600, Republic of Korea E-mail: [email protected], [email protected] We report controlled formation of sub-100 nm-thin electron channels in SrTiO3 by doping with oxygen vacancies induced by Ar+-ion irradiation. The conducting channels exhibit a consistent high electron mobility (~15,000 cm2V1s1), which enables clear observation of magnetic quantum oscillations, and gate-tunable linear magnetoresistance. Near the onset of electrical conduction, the metal-insulator transition is induced by the mobility suppression. With the high electron mobility and the ease of controlled channel formation, this ion-irradiation doping method may provide an excellent basis for developing oxide electronics. 1 Template for APEX (Jan. 2014) 1) SrTiO3 (STO) has the potential to become a key ingredient in oxide electronics owing to its intriguing electronic properties in addition to its versatility as a perovskite substrate for oxide heterostructures.2,3) The recent advancement in studies of the low-dimensional electronic system formed at the heterointerface between strontium titanate (STO) and 4) lanthanum aluminate (LaAlO3; LAO) has led to immense development and success in both understanding fundamental physics and developing new oxide electronic devices. When pure and stoichiometric, STO is an insulator with a large band gap of 3.2 eV. However, it can be made into an n-type conductor by substitutional doping with cations5,6) such as Nb and La or by introduction of oxygen vacancies.7) Especially, Ar+-ion irradiation on the crystal surface8-13) introduces oxygen vacancies and enables us to pattern conducting channels selectively on STO substrates using photolithography.

Ogale and R. Ramesh NSF-MRSEC on Oxides and Surfaces, and Centre for Superconductivity Research, Department of Physics, University of Maryland, College Park, MD 20742, USA Since the rejuvenation of interest in the rare earth manganites owing to their poten- tial use as magnetoresistive sensors, there has been adequate research to arrive at some evaluation of the potential for these materials in a variety of technologies that would use the peculiar properties of these materials. The magnetic field sensitivity of the transport properties, the strong metal insulator transition at the Curie temper- ature, the electric field polarizability of the material and its subsequent effect on the transport properties, the half metallicity of the electronic bands, etc., are properties of the rare earth manganites that could be exploited in a variety of devices. In this review we explore the various interesting technological avenues that are being pur- sued and address the uniqueness of the material that may enable a given technology as well as the various bottlenecks that will have to be overcome in order to suc- cessfully compete with the existing technologies. As is the case with many emerging materials technologies, the devices also serve as a vehicle for further understanding of the fundamental mechanisms behind the basic properties of the materials.

The wet chemical method, polymer complexing route, was used to prepare the precursor powders. To further investigate the polymer complexing method, it was also applied to the preparation of lanthanum aluminate based oxides. Single perovskite phase La0.8Sr0.2Ga0.83Mg0.17O2.815 can be prepared by the polymer complexing method using PVA as complexing agent. The thermal decomposition of the precursor powder undergoes three stages. While complete decomposition of the precursor is obtained at 1000°C. Further investigation of LaGaO3 doped with various amounts Sr or/and Mg was conducted. Three secondary phases were identified by X- ray diffraction, e.g.

  • Sign Reversal of Magnetoresistance in a Perovskite Nickelate by Electron Doping

Box 603, Beijing 100190, China 5School of Engineering and Applied Sciences, Harvard University, Cambridge, Massachusetts 02138, USA 6School of Electrical and Computer Engineering, Purdue University, West Lafayette, Indiana 47907, USA (Received 31 July 2016; revised manuscript received 14 November 2016; published 9 December 2016) We present low temperature resistivity and magnetotransport measurements conducted on pristine and electron doped SmNiO3 (SNO). The low temperature transport in both pristine and electron-doped SNO shows a Mott variable range hopping with a substantial decrease in localization length of carriers by one order in the case of doped samples. Undoped SNO films show a negative magnetoresistance (MR) at all temperatures characterized by spin fluctuations with the evolution of a positive cusp at low temperatures. In striking contrast, upon electron doping of the films via hydrogenation, we observe a crossover to a linear nonsaturating positive MR ∼ 0.2% at 50 K. The results signify the role of localization phenomena in tuning the magnetotransport response in doped nickelates. Ionic doping is therefore a promising approach to tune magnetotransport in correlated perovskites.

Perovskite oxides with cobalt B-site cations are particularly promising, as the range of the cation’s stable oxidation states leads to many possible structural frameworks. Here, we report growth of strontium cobalt oxide thin films by molecular beam epitaxy, and conditions necessary to stabilize different defect concentration phases. In situ X-ray scattering is used to monitor structural evolution during growth, while in situ X-ray absorption near-edge spectroscopy is used to probe oxidation state and measure changes to oxygen vacancy concentration as a function of film thickness. Experimental results are compared to kinetically limited thermodynamic predictions, in particular, solute trapping, with semiquantitative agreement. Agreement between observations of dependence of cobaltite phase on oxidation activity and deposition rate, and predictions indicates that a combined experimental/theoretical approach is key to understanding phase behavior in the strontium cobalt oxide system.

Maier Imperial College London, Department of Physics, Prince Consort Road, London SW7 2AZ, UK Keywords: plasmonic materials, optics, thin films, strontium molybdate, optical losses Strontium molybdate (SrMoO3) thin films are shown to exhibit plasmonic behaviour with a zero crossover wavelength of the real part of the dielectric permittivity tunable between 600 and 950 nm (2.05 eV and 1.31 eV). The films are grown epitaxially on strontium titanate (SrTiO3), magnesium oxide (MgO), and lanthanum aluminate (LaAlO3) substrates by pulsed laser deposition. SrMoO3 is shown to have optical losses lower than those of gold at the point at which the real part of the dielectric permittivity is equal to -2, while possessing low electrical resistivity of 100 μΩ cm at room temperature. Spectroscopic ellipsometry measurements reveal that SrMoO3 shows plasmonic behaviour, moreover we demonstrate that the epsilon near zero (ENZ) wavelength is tunable by engineering the residual strain in the films. The relatively broadband ENZ behaviour observed in SrMoO3 demonstrates its potential suitability for transformation optics along with plasmonic applications in the visible to near infrared spectral range.
