Scanning tunneling microscopy in liquid environment has gained an increased interest in recent years. The specific features of the in situ observation of surface structures at the solid/liquid interface are first presented. Next, a high resolution imaging of high oriented pyrolytic graphite (HOPG) graphite surface shows the potentiality of our home-made microscope. The last study, performed on technological InP. substrates, illustrates the extensive applications of in situ imaging in the fields of semiconductor technology.
