Moreover, controlling the positioning of two-dimensional crystals facilitates their integration in complex devices, which enables the exploration of novel applications and the discovery of new phenomena in these materials. To date, deterministic transfer methods rely on the use of sacrificial polymer layers and wet chemistry to some extent. Here, we develop an all-dry transfer method that relies on viscoelastic stamps and does not employ any wet chemistry step. This is found to be very advantageous to freely suspend these materials as there are no capillary forces involved in the process. Moreover, the whole fabrication process is quick, efficient, clean and it can be performed with high yield.

It is published daily online and monthly in print. APEX publishes articles dealing with the applications of physical principles as well as articles concerning the understanding of physics with particular applications in mind. However, as a letter journal, emphasis will be given to developing and emerging fields in applied physics. A work of high originality but concerning a field not in a competitive area may be suggested to be submitted to the Spotlights JJAP Communication section. Examples of fields of current interest include: Read the articles selected by the Editors as having high • Semiconductors, dielectrics and organic materials potential for capturing the • Photonics, quantum electronics, optics and spectroscopy interest of researchers in the • Spintronics, superconductivity and strongly correlated applied physics community materials • Device physics including quantum information processing • Nanoscale science and technology Impact Factor • Crystal growth, surfaces, interfaces, thin films and bulk materials • Plasmas, applied atomic and molecular physics, and 2.731 applied nuclear physics As listed in 2012 Journal Citation • Device processing, fabrication and measurement reports (Thomson Reuters 2012)® technologies, and instrumentation • Cross-disciplinary areas such as bioelectronics/ Published in partnership with: photonics, biosensing, environmental/energy The Japan Society of Applied Physics technologies and MEMS iopscience.org/apex 8 iopscience.org/graphene FEATURED ARTICLE Fully valley- and spin-polarized magnetocapacitance in n-type monolayer MoS2 Xiaoying Zhou, Yiman Liu, Ma Zhou, Huaihua Shao and Guanghui Zhou 2014 Appl. Phys. Express 7 021201 Abstract We present a theoretical investigation on the quantum magnetocapacitance (MC) for n-type monolayer MoS2 under a perpendicular magnetic field. We find that the MC clearly reflects the valley- and spin- resolved Landau levels (LLs). Interestingly, the MC is fully valley- and spin-polarized, which results in perfect square-wave-shaped polarization. This fully valley- and spin-polarized MC, especially the peak corresponding to the lowest LL, may be of great significance in valleytronic and spintronic device applications because it provides a magnetic method to control the electron valley and spin degrees of freedom. The MC behavior as a function of the magnetic field is also discussed.
