Paul Wang, Professor

Dr. Wang joined the Physics Department in 2001 coming from the University of Texas at El Paso.

Dr. Wang Discusses His Research

My research area is focused on semiconductor, optoelectronic, and optical materials.  Currently I am working on the growth atomic thin layers of Group IV element onto Si/Ge surfaces by using low temperature Chemical Vapor Deposition (CVD) or Molecular Beam Epitaxy (MBE).  The surface chemical reactions will be deliberately controlled by low energy electrons/photons in order to remove unwanted species and leave desired atoms behind on the substrate.  Since the nanometer size aggregates/islands can be easily formed on the substrate the microscope equipped with atomic resolution will provide more information about the growth mechanism of atomic thin layer.  My near future research will focus on the alloy used in engines as well.  Thin films of AlTi dopes with Nb and of super Ni alloys will be fabricated by MBE, and their surface reactions can be investigated in situ in the ultra-high vacuum chamber.  My collaborators in the department are Profs. Craig, Kimberlin and Roos.

Teaching

Courses at UTEP and Bradley

Co-P.I. in a project associated with the NSF-funded Minority Research Center of Excellence in Materials Science at UTEP. Mentored minority students and women (Melissa, Borgen, Saucedo, Judi Sulak, Jorge Garcia, Lisa Barrett, and Marco Avila) in this program through the B.S. and M.S. degree programs.

P.I. for several other projects, one of them entitled "Growth Conditions for Surface Oxides on Aluminum Alloys", with NASA, one M.S. and one B.S. students were graduated in this program.

P.I. for projects such as metal doped glasses funded by Space and Naval Warfare Systems Command, Institute for Manufacturing and Materials Management (IM3), and Texas Centers for Business and Enterprise Development. Several students and one postdoc were graduated/supported from these projects.

Recipient, along with three Physics faculty members at Bradley, of an RUI/NSF grant entitled "Issues in Ultra Thin Film Growth on Group IV Semiconductors".
