Microscope:
Home Built UHV 4K STM

Controls:
SPM 1000 Control System

The experiment was carried out in UHV with a home build 4K STM using a Femto preamplifier and the RHK SPM1000. The images shows 17 Fe atoms on Cu(111) which were laterally manipulated with the STM to form the letters PI.

Cl-induced etching of Si(100)-(2×1) under conditions of super-saturation. A saturated surface was heated to 800 K while being exposed to a Cl2 flux to facilitate Cl insertion into dimer bonds. The dark lines are etch pits in the top layer that were produced by a new reaction pathway
