Excess electron screening of remote donors and mobility in modern GaAs/AlGaAs herostructures
M. Sammon, Tianran Chen, B. I. Shklovskii
In modern GaAs/AlGaAs heterostructures with record high mobilities, a two-dimensional electron gas (2DEG) in a quantum well is provided by two remote donor -layers p…
Theory of a field effect transistor based on semiconductor nanocrystal array
K. V. Reich, Tianran Chen, B. I. Shklovskii
We study the surface conductivity of a field-effect transistor (FET) made of periodic array of spherical semiconductor nanocrystals (NCs). We show that electrons introduced to NCs…
Photoluminescence in array of doped semiconductor nanocrystals
K. V. Reich, Tianran Chen, Al. L. Efros +1
We study the dependence of the quantum yield of photoluminescence of a dense, periodic array of semiconductor nanocrystals (NCs) on the level of doping and NC size. Electrons intro…
Effect of bulk charged impurities on the bulk and surface transport in three-dimensional topological insulators
Brian Skinner, Tianran Chen, B. I. Shklovskii
In the three-dimensional topological insulator (TI), the physics of doped semiconductors exists literally side-by-side with the physics of ultra-relativistic Dirac fermions. This u…
Why is the bulk resistivity of topological insulators so small?
Brian Skinner, Tianran Chen, B. I. Shklovskii
As-grown topological insulators (TIs) are typically heavily-doped -type crystals. Compensation by acceptors is used to move the Fermi level to the middle of the band gap, but ev…
Coulomb gap triptych in a periodic array of metal nanocrystals
Tianran Chen, Brian Skinner, B. I. Shklovskii
The Coulomb gap in the single particle density of states (DOS) is a universal consequence of electron-electron interaction in disordered systems with localized electron states. Her…
