1. 1. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Author : Louise Olausson; [2022]
   Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

   Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

   Abstract : LBIC is a technique for scanning the local quantum efficiency of solar cells. This kind of measurements needs a highly specialized, and time critical controlling software. In 1996 the client, professor Markus Rinio, constructed an LBIC system, and wrote the controlling software as a Turbo-Pascal 7.0 application, running under the MS-DOS 6. READ MORE
