Laser thermal spectroscopy of highly granular NbN
Description
The temperature dependence of far-infrared transmission gives 2Δ(O), T/sub c/, and evidence of fluctuations in NbN films. Homogeneous and highly granular (R/sub D'Alembertian/ = 21 000 Ω) NbN are found to be equally strong coupled. BCS theory predicts a peak in transmission-versus-temperature curves which is observed at a reduced level in a homogeneous sample and vanishes completely in the granular material. The extinction of the peak is ascribed to zero-dimensional fluctuations near T/sub c/
