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

Home-built atomic force microscope in a He-3 cryostat

Controls:

Description:
Single-electron charging events of a quantum dot that forms in a semiconducting carbon nanotube at temperature T=4K, visualized by an atomic force microscope using resonance frequency shift microscopy. The quantum dot is located at the center of the concentric rings. As the tip moves towards the quantum dot, a single electron tunnels onto the quantum dot each time the tip crosses a dark line.
