Alexander A. Balandin Biography

Alexander A. Balandin is currently professor of electrical engineering and founding chair of materials science and engineering at the University of California, Riverside (UCR). He received his M.S. (1991) summa cum laude in applied physics and mathematics from the Moscow Institute of Physics and Technology (MIPT), Russia, and Ph.D. (1997) in electrical engineering from the University of Notre Dame. Prior to joining UCR, he worked as a research engineer at UCLA. In 2005, he spent his sabbatical as a visiting professor at the University of Cambridge, U.K. His research interests are in the area of advanced materials, nanostructures and nanodevices for electronic, optoelectronic and direct energy conversion applications. He conducts both experimental and theoretical research. His work resulted in over 190 journal publications, which were cited ~13,500 times (h>55). Professor Balandin is a recipient of the IEEE Pioneer Award in Nanotechnology for 2011. He was recognized by the National Science Foundation CAREER Award, ONR Young Investigator Award, UC Regents Award, and Merrill Lynch Innovation Award. He is a Fellow of the American Physical Society, Optical Society of America, IEEE, SPIE and the American Association for the Advancement of Science. He is an Editor of IEEE Transactions on Nanotechnology and an associate editor of Applied Physics Letters. He supervised more than 20 Ph.D. students who presently carry out R&D work in industry, government laboratories and academia. The work of his Nano-Device Laboratory (NDL) has been supported by NSF, DARPA, ONR, AFOSR, SRC, NASA and the semiconductor industry.

Talk Presentation: Phonons in Graphene and van der Waals Materials

Phonons—quanta of crystal lattice vibrations—reveal themselves in all electrical, thermal and optical phenomena in materials. Acoustic phonons carry heat and limit electron mobility while optical phonons affect the light - matter interactions. Nanostructures open opportunities for tuning the phonon spectrum and related properties of materials for specific applications, thus realizing what was termed phonon engineering or nanophononics. A recent advent of graphene and quasi two-dimensional van der Waals materials resulted in a discovery of a wealth of new phonon physics and created opportunities for better control of phonon transport and interactions. In this talk, I described the measurements of the phonon thermal conductivity of graphene using the optothermal Raman technique; explained physical phenomena leading to the anomalous behavior of the thermal conductivity of graphene; and outlined practical applications of graphene in thermal management of electronic devices and circuits. The unique phonon properties of a broad class of van der Waals materials and semiconductor nanostructures were also discussed. Specifically, I addressed the issues of increasing the thermoelectric figure of merit in stacks of layered materials, modification of the transition temperature to the charge-density-wave phase and the use of Raman spectroscopy as nanometrology tool for quasi two-dimensional crystals.
