Electrostatic Tuning of the Properties of Disordered Indium Oxide Films near the Superconductor-Insulator Transition
Yeonbae Lee, Aviad Frydman, Tianran Chen +2
The evolution with carrier concentration of the electrical properties of amorphous indium oxide (InO) thin films has been studied using electronic double layer transistor configura…
Anomalously small resistivity and thermopower of strongly compensated semiconductors and topological insulators
Tianran Chen, B. I. Shklovskii
In the recent paper we explained why the maximum bulk resistivity of topological insulators (TIs)is so small [B. Skinner, T. Chen, and B. I. Shklovskii, Phys. Rev. Lett. 109, 17680…
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 triptychs, effective charge, and hopping transport in periodic arrays of superconductor grains
Tianran Chen, Brian Skinner, B. I. Shklovskii
In granular superconductors, individual grains can contain bound Cooper pairs while the system as a whole is strongly insulating. In such cases the conductivity is determined by el…
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…
Theory of hopping conduction in arrays of doped semiconductor nanocrystals
Brian Skinner, Tianran Chen, B. I. Shklovskii
The resistivity of a dense crystalline array of semiconductor nanocrystals (NCs) depends in a sensitive way on the level of doping as well as on the NC size and spacing. The choice…
