Superconducting proximity effect in InAsSb surface quantum wells with in-situ Al contact
William Mayer, William F. Schiela, Joseph Yuan +9
We demonstrate robust superconducting proximity effect in InAsSb quantum wells grown with epitaxial Al contact, which has important implications for mesoscopic and…
Electrical tuning of helical edge states in topological multilayers
T. Campos, M. A. T. Sandoval, L. Diago-Cisneros +1
Mainstream among topological insulators, GaSb/InAs quantum wells present a broken gap alignment for the energy bands which supports the quantum spin Hall insulator phase and forms…
Ultralong spin lifetimes in one-dimensional semiconductor nanowires
Florian Dirnberger, Michael Kammermeier, Jan König +9
We experimentally demonstrate ultralong spin lifetimes of electrons in the one-dimensional (1D) quantum limit of semiconductor nanowires. Optically probing single wires of differen…
Spin-orbit coupling effects in zinc-blende InSb and wurtzite InAs nanowires: Realistic calculations with multiband method
Tiago Campos, Paulo E. Faria Junior, Martin Gmitra +2
A systematic numerical investigation of spin-orbit fields in the conduction bands of III-V semiconductor nanowires is performed. Zinc-blende InSb nanowires are considered along [00…
Stability and accuracy control of parameters
Carlos M. O. Bastos, Fernando P. Sabino, Paulo E. Faria Junior +3
The method is a successful approach to obtain band structure, optical and transport properties of semiconductors, and it depends on external parameters that ar…
Realistic multiband k.p approach from ab initio and spin-orbit coupling effects of InAs and InP in wurtzite phase
Paulo E. Faria Junior, Tiago Campos, Carlos M. O. Bastos +3
Semiconductor nanowires based on non-nitride III-V compounds can be synthesized under certain growth conditions to favor the appearance of wurtzite crystal phase. Despite the repor…
Interband polarized absorption in InP polytypic superlattices
P. E. Faria Junior, T. Campos, G. M. Sipahi
Recent advances in growth techniques have allowed the fabrication of semiconductor nanostructures with mixed wurtzite/zinc-blende crystal phases. Although the optical characterizat…
