Photoresponses of ZnO nanobridge devices fabricated using a single-step thermal evaporation method. Sens. Actuators B: Chem., 126(1), 73-77.

, crystallinity and chemical composition of the as grown antimony film [ 10 ]. The grown film was further tested for radiation detection. The photoresponse of the film was evaluated using its current-voltage characteristics. Fig. 2 (a) Schematic of the physical vapor deposition reactor, (b) temperature gradient measured inside the furnace tube. 3 Results and discussion 3.1 Temperature gradient Before starting the growth process, it was necessary to measure the temperature gradient in the furnace tube. The furnace temperature was raised to 900 °C and temperature gradient was
