A number of different methods for electrically characterizing ZnSe thin films are presented. These include the Hall effect, current-voltage profiling, and capacitance-voltage profiling. The planar Schottky technique is ...

The time dependence of the carrier relaxation in undoped solid C$\sb{60}$ thin films has been studied by monitoring changes in the optical transmission upon photoexcitation using sub picosecond laser pulses at 2 eV. Optical ...
