Making faster, more powerful electronics requires smaller but still uniform connections, or junctions, between different materials. For the first time, researchers created extremely small, 5-nanometer-wide junctions, which ...
Epitaxy, or growing crystalline film layers that are templated by a crystalline substrate, is a mainstay of manufacturing transistors and semiconductors. If the material in one deposited layer is the same as the material ...
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combined two different ultrathin ...
(Phys.org)—The performance of all of today's electronic devices depends on the quality of the semiconductor materials they're made of. Two of the most important factors that affect a semiconductor's properties are its band ...
A quantum mechanical transport phenomenon demonstrated for the first time in synthetic, atomically-thin layered material at room temperature could lead to novel nanoelectronic circuits and devices, according to researchers ...
When electronic states in materials are excited during dynamic processes, interesting phenomena such as electrical charge transfer can take place on quadrillionth-of-a-second, or femtosecond, timescales. Numerical simulations ...
Two-dimensional (2D) layered materials are now attracting a lot of interest due to their unique optoelectronic properties at atomic thicknesses. Among them, graphene has been mostly investigated, but the zero-gap nature of ...
(Phys.org) —Scientists from SLAC, Stanford and Berkeley Lab grew sheets of an exotic material in a single atomic layer and measured its electronic structure for the first time. They discovered it's a natural fit for making ...
When scientists remove individual atoms in a semiconductor material, the resulting vacancies become point defects. Contrary to what their name implies, these defects can have beneficial effects on the semiconductor's properties ...
(Phys.org) —The mention of a two-dimensional material with excellent electrical and optical properties may first bring to mind graphene. However, this description also fits another class of materials called transition metal ...
