Temperature inversion on the surface of externally heated optically thick multigrain dust clouds [PDF]

open access: yes, 2006
It was recently discovered that the temperature in the surface layer of externally heated optically thick gray dust clouds increases with the optical depth for some distance from the surface, as opposed to the normal decrease in temperature with distance

Band gap control via tuning of inversion degree in CdIn$_2$S$_4$ spinel [PDF]

open access: yes, 2012
Based on theoretical arguments we propose a possible route for controlling the band-gap in the promising photovoltaic material CdIn$_2$S$_4$. Our \textit{ab initio} calculations show that the experimental degree of inversion in this spinel (fraction of ...
