Developing high efficiency Cu2ZnSnS4 (CZTS) thin film solar cells by sputtering
… have been studied. The “epitaxial” CdS/CZTS interface and moderate Cd diffusion effects were discovered, found to play critical roles in improving the cell efficiency. Thirdly, the conduction band alignments of different buffer materials with CZTS have been carefully investigated. Conduction …

One- and two-qubit operations in Si-MOS quantum dots
… dot qubits in the presence of a step at a hetero-interface. We calculate single qubit gate times of 170 ns for a quantum dot confined at a silicon/silicon-dioxide interface. To understand the origin of spin-orbit coupling, we experimentally probe the g-factor for two quantum dot qubits as a …

Platform for monolithic integration of III-V devices with Si CMOS technology
… This structure is composed of a standard NiSi/Si interface and novel Si/III-V interface. Specific contact resistivity of the double hetero-interface stack can be tuned by controlling Si/IIIV band alignments at the epitaxial growth interface. P-type Si/GaAs interfaces and n-type Si/InGaAs …

Auger-mediated processes and photoluminescence in group iv semiconductor nanostructures
… is observed. The influence of the Si/SiO_2 interface on the recombination mechanism in this system is emphasized. Results of the experiments show that the coexistence of a type II energy band alignment at Si/SiGe interfaces, the electron-hole-droplets in Si, and Auger-mediated processes …
