Topological sliding moiré heterostructure [PDF]

Physical Review B, 2020
We investigate the effect of sliding motion of layers in Moir heterostructures on the electronic state. We show that the sliding Moir heterostructure can generate nontrivial topology characterized by the first and second Chern number in the high dimensional manifold spanned by the physical dimensions and synthetic dimensions associated with the ...

Semiconductor nanowire heterostructures [PDF]

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004
Recent progress on the synthesis and characterization of semiconductor nanowire heterostructures is reviewed. We describe a general method for heterostructure synthesis based on chemical vapour deposition and the vapour-liquid-solid growth of crystalline semiconducting nanowires.

Design approaches and materials processes for ultrahigh efficiency lattice mismatched multi-junction solar cells [PDF]

, 2006
In this study, we report synthesis of large area (>2cm^2), crack-free GaAs and GaInP double heterostructures grown in a multi-junction solar cell-like structure by MOCVD. Initial solar cell data are also reported for GaInP top cells.

Highly efficient spin-orbit torque and switching of layered ferromagnet Fe3GeTe2 [PDF]

, 2019
Among van der Waals (vdW) layered ferromagnets, Fe3GeTe2 (FGT) is an excellent candidate material to form FGT/heavy metal heterostructures for studying the effect of spin-orbit torques (SOT).

STM/STS Study of the Density of States and Contrast Behavior at the Boundary between (7 × 7)_N and (8 × 8) Structures in the SiN/Si(111) System

Crystals, 2022
The origin of the contrast appearing in STM images at the boundary between diverse ordered structures is studied using the example of two structures, (7 × 7)N and (8 × 8), formed in the system of a two-dimensional silicon nitride layer on the Si(111 ...
