Two?Dimensional Silicene–Stanene Heterostructures by Epitaxy

Chemical Beam Epitaxy of Iii-v Semiconductor Heterostructures

Prismatic quantum heterostructures synthesized on molecular-beam epitaxy GaAs nanowires.

Semiconductor nanowires have stimulated extensive interest in the last decade because of their potential use as building blocks in future generations of electronic and optoelectronic applications. Equally important, their singular geometry provides an opportunity to test fundamental quantum mechanical concepts and related phenomena. Even though significant advances have been made in the synthes...

Arrayed van der Waals Vertical Heterostructures Based on 2D GaSe Grown by Molecular Beam Epitaxy.

Vertically stacking two-dimensional (2D) materials can enable the design of novel electronic and optoelectronic devices and realize complex functionality. However, the fabrication of such artificial heterostructures on a wafer scale with an atomically sharp interface poses an unprecedented challenge. Here, we demonstrate a convenient and controllable approach for the production of wafer-scale 2...

Properties and applications of quantum dot heterostructures grown by molecular beam epitaxy

One of the main directions of contemporary semiconductor physics is the production and study of structures with a dimension less than two: quantum wires and quantum dots, in order to realize novel devices that make use of low-dimensional confinement effects. One of the promising fabrication methods is to use self-organized three-dimensional (3D) structures, such as 3D coherent islands, which ar...

Localized variations in electronic structure of AlGaNÕGaN heterostructures grown by molecular-beam epitaxy

Local electronic properties in a molecular-beam-epitaxy-grown AlxGa12xN/GaN heterostructure field-effect transistor epitaxial layer structure are probed using depth-resolved scanning capacitance microscopy. Theoretical analysis of contrast observed in scanning capacitance images acquired over a range of bias voltages is used to assess the possible structural origins of local inhomogeneities in ...
