Advanced Materials > 34 > 33 > n/a - n/a

In superconducting quantum circuits, aluminum is one of the most widely used materials. It is currently also the superconductor of choice for the development of topological qubits. However, aluminum‐based devices suffer from poor magnetic field compatibility. Herein, this limitation is resolved by showing that adatoms of heavy elements (e.g., platinum) increase the critical field of thin aluminum...

Semiconducting–superconducting hybrids are vital components for the realization of high‐performance nanoscale devices. In particular, semiconducting–superconducting nanowires attract widespread interest owing to the possible presence of non‐abelian Majorana zero modes, which are quasiparticles that hold promise for topological quantum computing. However, systematic search for Majoranas signatures...

2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS)]

The basic ingredients for spintronics using semiconductor nanowires are discussed. For spin manipulation spin-orbit coupling is employed. In this respect the effect of the Rashba and Dresselhaus contributions are investigated. The strength of spin-orbit coupling is extracted by measuring the weak anti-localization effect and comparing the experimental results to a theoretical model. On nanowires covered...
