Investigation new sensing SnTiO3 as thin film light sensor
In this project, some research has been done on Tin dioxide (SnO2) and stannium titanate perovskite (SnTiO3) thin films. It has been known that tin dioxide has various applications, especially for gas sensor, light sensor, pressure sensor and humidity sensor. Main purpose of this project is to fabri...
