Abstract

Vanadium dioxide (VO2) film which has nearly the same transition point as single crystal has been obtained by reactive evaporation of vanadium on glass and subsequent annealing in N2 gas. Relations between optical properties of VO2 film and its preparation conditions are presented. We made optical direct bit recording on VO2 film using a laser diode as the light source. The threshold recording energy and bit density are 2 mJ/cm2 and 350 bits/mm, respectively. We also made tungsten doping to lower the VO2 film transition temperature.
