Time-Resolved Spectroscopy of Single Excitons Bound to Pairs of Te Isoelectronic Impurity Centers in ZnSe
A. Muller, P. Bianucci, C. Piermarocchi +4
Tellurium impurity centers in ZnSe were individually probed with time-resolved photoluminescence (PL) spectroscopy. Resolution-limited peaks with an ultra-low spatial density origi…

Wannier-functions characterization of floating bonds in a-Si
M. Fornari, N. Marzari, M. Peressi +1
We investigate the electronic structure of over-coordinated defects in amorphous silicon via density-functional total-energy calculations, with the aim of understanding the relatio…
