Dual-adatom diffusion-limited growth model for compound nanowires: Application to InAs nanowires
Danylo Mosiiets, Yann Genuist, Joël Cibert +2
We propose a dual-adatom diffusion-limited model for the growth of compound semiconductor nanowires via the vapor-liquid-solid or the vapour-solid-solid mechanisms. The growth is c…
First Principles Assessment of CdTe as a Tunnel Barrier at the -Sn/InSb Interface
Malcolm J. A. Jardine, Derek Dardzinski, Maituo Yu +9
Majorana zero modes, with prospective applications in topological quantum computing, are expected to arise in superconductor/semiconductor interfaces, such as -Sn and InSb. Howe…
Role of a capping layer on the crystalline structure of Sn thin films grown at cryogenic temperatures on InSb substrates
