Vasili Perebeinos Research Staff Member IBM Research Division T. J. Watson Research Center P. O. Box 218 Yorktown Heights, NY 10598 tel: 914-945-3567 email: vperebe@us.ibm.com

I graduated from the  Kolmogorov High School N2 in 1991.  In the same year I entered the Physics Department of Moscow State University, where I was doing research in plasma physics and supervised by professor A. A. Rukhadze. In 1997 I graduated with excellence and became a student of the Physics Department at SUNY at Stony Brook.  In March 2001 I defended a PhD thesis guided by professor Philip B. Allen. April 2001 - June 2003  I was at  Physics Department   at Brookhaven National Laboratory as a research a Research Associate in the condensed matter theory group. In June 2003 I joined Nanoscale Science and Technology Group at IBM T.J. Watson Research Center.

I am interested in transport and optical properties of carbon nanotubes. I am using both model Hamiltonian and first principle Density Functional Theory methods  to address the issues of transport and optical properties of low dimensional systems like carbon nanotubes.
Excitons dominate the absorption spectra in carbon nanotubes. To describe excitons in carbon nanotubes I solve  Bethe-Salpeter-Equation for the two particle electron-hole wavefunction.
Carbon nanotubes are known for very high mobility at low fields which makes them very attractive for the electronic device applications. I predict the mobility in carbon nanotubes using the microscopic theory for the inelastic electron-phonon scattering.
