Coherent control of thermal transport with pillar-based phononic crystals
Tatu A. S. Korkiamäki, Tuomas A. Puurtinen, Mikko Kivekäs +4
Two-dimensional phononic crystals (PnCs) formed by a periodic array of holes in a suspended membrane have previously been used to coherently control thermal conductance at low temp…

Improvement of the Simmons model for tunnel junctions
Ilmo Räisänen, Ilari Maasilta
The Simmons model is a well-known and widely used model for the elastic tunneling current of a metallic tunnel junction, and fitting it to electrical measurements can be used to es…
