A crystal cleavage mechanism for UHV STM
  A device for UHV cleavage of crystal specimens for the use with STM has been suggested and developed. We present a device suitable for the precise cleavage of semiconductors. The device needs only small space and can be easily mounted in a small and compact UHV chamber equipped with a wobble stick manipulator. In order to prove the technique UHV STM measurements on InAs(110) surfaces with different bulk conductivities (p-and n-type) have been performed.
