Impressive Reduction of Dark Current in InSb Infrared Photodetector to achieve High Temperature Performance

Infrared photo detectors have vast and promising applications in military,industrial and other fields. In this paper, we present a method for improving theperformance of an infrared photodetector based on an InSb substance. To achieve goodperformance at high temperatures, thermal noise and intrusive currents should bereduced. For this purpose, a five-layer hetero structu...

Coherent Charge Transport in Ballistic InSb Nanowire Josephson Junctions.

Hybrid InSb nanowire-superconductor devices are promising for investigating Majorana modes and topological quantum computation in solid-state devices. An experimental realisation of ballistic, phase-coherent superconductor-nanowire hybrid devices is a necessary step towards engineering topological superconducting electronics. Here, we report on a low-temperature transport study of Josephson jun...

Scattering in Nanoscale Devices

In this thesis electronic transport through nanoscale devices is modeled by means of quantum physics. Moving from ballistic transport towards a detailed description of electron-phonon scattering, the used formalism changes from wave functions to the non-equilibrium Green’s functions (NEGF). The simulation framework consists of the quantum mechnical simulator SIMNAD, which was developed at the I...
