Two dimensional crystals in three dimensions: electronic decoupling of single-layered platelets in colloidal nanoparticles
Roman Kempt, Agnieszka Kuc, Jae Hyo Han +2
Two-dimensional crystals, single sheets of layered materials, often show distinct properties desired for optoelectronic applications, such as larger and direct band gaps, valley- a…
High-performance two-dimensional p-type transistors based on GaSe layers: an ab-initio study
Agnieszka Kuc, Teresa Cusati, Elias Dib +5
Ultrascaled GaSe field effect transistors are investigated through ab initio calculations. GaSe monolayers, 3 nm long, exhibit excellent performance with reduced short-channel effe…
Two-Dimensional Ferroelastic Topological Insulators in Single-Layer Janus Transition Metal Dichalcogenides MSSe (M=Mo, W)
Yandong Ma, Liangzhi Kou, Baibiao Huang +2
Two-dimensional topological insulators and two-dimensional materials with ferroelastic characteristics are intriguing materials and many examples have been reported both experiment…
Highly sensitive electromechanical piezoresistive pressure sensors based on large-area layered PtSe films
Stefan Wagner, Chanyoung Yim, Niall McEvoy +8
Two-dimensional (2D) layered materials are ideal for micro- and nanoelectromechanical systems (MEMS/NEMS) due to their ultimate thinness. Platinum diselenide (PtSe), an excit…
Transport of hydrogen isotopes through interlayer spacing in van der Waals crystals
S. Hu, K. Gopinadhan, A. Rakowski +7
Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one…
