Profile:
    Francisco is a second year PhD student in the materials department where he is also advised by Art Gossard . He has taken over the responsibilities of Ted Kreutz in the Lab, which involves growing GaAs and GaMnAs crystals we need for our spintronics experiments using MBE (molecular beam epitaxy). He also is involved in doing electronic transport experiments on materials with adsorbed SAMs (self assembled monolayers), in order to determine the electronic interaction that occurs when SAMs bind to the surface of GaAs.  He is also kept busy improving our measurement capabilities in electro-magneto transport lab.
    Update 05/05:  Francisco has begun a new project investigating tunneling through MnAs particles placed at a PN junction.  These particles are of interest since they are ferromagnetic above room temperature and can be incorporated in GaAs while imparting few defects.  These particles show promise for use in spintronics devices.

Cheyne Scoby
     
Physics Junior

Profile:
Cheyne is a third year undergraduate physics major (BS) in the College of Letters and Sciences at UC Santa Barbara. He has worked as an assistant with the Gwinn group since April 2004. His projects have included mechanical design and the machining of lab equipment, and using various methods such as contact angle measurement, ellipsometry, and x-ray photoelectron spectroscopy to determine surface quality of prepared samples. Outside the lab, he serves as secretary for the local Society of Physics Students chapter and sings tenor in the UCSB chamber choir. After graduation from UCSB, Cheyne plans to attend graduate school in high energy physics.
