【Abstract】 New self-made instrument for measuring thin film resistance using four-probe method with varying temperature(from room temperature to 300 ℃) under rough vacuum was introduced.It was suitable for the development of physics experiments on properties related to the temperature-dependent resistance,for example,the resistance v.s.temperature characteristic of metal and semiconductor thin film and thermal-lag effect of vanadium dioxide thin film,and so on.更多还原
