Investigation on spin speed of tin oxide (SnO2) thin film via spin coating technique for solar application / Nur Elisa Azmi

This thesis investigates the relationship between thickness, resistivity, conductivity and the surface roughness of Tin Oxide (SnCh) by using sol-gel spin coating technique. Sn02 thin film were deposited onto glass substrates via sol-gel spin coating technique with different spin speed. The thin fil...
