Popis: A scanning tunneling microscope which uses a gallium arsenide tip has been successfully constructed. Atomic resolution is demonstrated by the imaging of the Si(111)‐7×7 surface in ultrahigh vacuum. Details of the tip preparation are given and the tip tunneling current characteristics are discussed.
