Alkali specific effects in superconducting fullerides: the observation of a high temperature insulating phase in Na_2CsC_60
Natasa Cegar, Ferenc Simon, Slaven Garaj +5
Electron Spin Resonance and optical reflectivity measurements demonstrate a metal-insulator transition in Na_2CsC_60 as the system passes from the low temperature simple cubic to t…

Excitonic lasing in semiconductor quantum wires
L. Sirigu, D. Y. Oberli, L. Degiorgi +2
Direct experimental evidences for excitonic lasing is obtained in optically pumped V-groove quantum wire structures. We demonstrate that laser emission at a temperature of 10 K ari…
