Electron spin resonance and electrical properties of co-evaporated SiO/SnO2 thin films

Electron spin resonance (ESR) measurements are reported for various compositions of SiO/SnO2 thin films and indicate a decrease in the value of spin density for increasing SnO2 content in the SiO. Annealing of the device further reduces the value of the spin density. The electrical activation energy and resistivity have been found to increase after annealing of the device and the results are compared with the optical and ESR measurements.
