Research Interests

My current research interests are directed towards atomic scale devices fabricated with phosphorous dopants in Silicon. The placement of the dopants is achieved by lithography with a Scanning Tunneling Microsopce (STM) on a hydrogen resist and subsequent phosphine dosing. Recently, I have been investigating the atomic scale electronic properties of phosphorous atoms in Si(001) with Scanning Tunneling Microscopy and Spectroscopy (STS).

For my PhD thesis I have studied the nanoscale electronic properties using STM/STS of a variety of semiconductor heterostructures: Schottky barrier formation at metal contacts on GaAs, pn junctions in GaAs, carbon dopants in GaAs in homogeneous and delta-doped layers, structural and electronic properties of AlGaAs-quantum wells and InAs-quantum dots, ordering in ternary and quaternary compound III-V semiconductors.
