Phys Rev Lett. 2012 Mar 09;108(10):107006. doi: 10.1103/PhysRevLett.108.107006. Epub 2012 Mar 09.

Continuous, coherent subterahertz radiation arises when a dc voltage is applied across a stack of the many intrinsic Josephson junctions in a Bi2Sr2CaCu2O(8+δ) single crystal. The active junctions produce an equal number of I-V characteristic branches. Each branch radiates...

Adv Mater. 2017 Oct;29(37). doi: 10.1002/adma.201701836. Epub 2017 Aug 14.

A superconducting hard gap in hybrid superconductor-semiconductor devices has been found to be necessary to access topological superconductivity that hosts Majorana modes (non-Abelian excitation). This requires the formation of homogeneous and barrier-free interfaces between the superconductor and semiconductor. Here,...
