SrTiO_3负载FeSe单层薄膜中超大能隙的发现引发了人们对晶体表面制备的表面增强超导薄膜的研究兴趣。由于超薄膜在空气中的不稳定性，需要在超高真空（UHV）下进行电输运测量。本文综述了原位电输运测量的实验技术及其在薄膜电输运研究中的应用。
The discovery of an extraordinarily superconductive large energy gap in SrTiO3 supported single-layer FeSe films has recently initiated a great deal of research interests in surface-enhanced superconductivity and superconductive ultrathin films fabricated on crystal surfaces. On account of the instability of ultra-thin films in air, it is desirable to perform electrical transport measurement in ultra-high vaccum (UHV). Here we review the experimental techniques of in situ electrical transport measurement and their applications on superconductive ultrathin films.
