Formation of Strain-Induced Quantum Dots in Gated Semiconductor Nanostructures
Ted Thorbeck, Neil M. Zimmerman
Elastic strain changes the energies of the conduction band in a semiconductor, which will affect transport through a semiconductor nanostructure. We show that the typical strains i…
Quasiparticle scattering from topological crystalline insulator SnTe (001) surface states
Duming Zhang, Hongwoo Baek, Jeonghoon Ha +5
Recently, the topological classification of electronic states has been extended to a new class of matter known as topological crystalline insulators. Similar to topological insulat…
Chern insulator at a magnetic rocksalt interface
Kevin F. Garrity, David Vanderbilt
Considerable efforts have recently been devoted to the experimental realization of a two-dimensional Chern insulator, i.e., a system displaying a quantum anomalous Hall effect. How…
First-Principles Studies of the Atomic, Electronic, and Magnetic Structure of a-MnO2 (Cryptomelane)
Eric Cockayne, Lan Li
Density functional theory calculations are used to investigate a-MnO2, a structure containing a framework of corner and edge sharing MnO6 octahedra with tunnels in between. Placing…
