Construction of a simple scanning tunneling microscope (STM) is described. This STM is suitable for atmospheric, controlled atmosphere, and high vacuum (but not UHV) work. This STM is especially wen suited for determining ...

Electrochemically etched tungsten scanning tunneling microscope (STM) tips are dc sputter coated with 20 nm of gold (0.04 rim/s and 10 mTorr of argon). Transmission electron microscope (TEM) images of typical etched tips ...
