接触电势差 meaning in English

contact potential difference

To achieve accurate detection of surface potential , the measurement of the contact potential difference of the zno / si step was also carried out . polarization - related surface properties of ferroelectric thin films were investigated by kelvin probe force microscopy ( kpfm ) , leading to the discovery of asymmetric charge writing on the surface of pb ( zr _ ( 0 . 55 ) ti _ ( 0 . 45 ) ) o _ 3 ( pzt ) thin film
为了优化仪器的检测灵敏度和稳定性,选用氧化锌薄膜上的zno / si台阶作为测试对象,检测了zno / si的接触电势差;通过改变仪器系统参数,发现针尖-样品距离和扫描速度对接触电势差的检测结果影响显著。
