We synthesize and characterize nanoscale materials (graphene, MoS2, single-walled carbon nanotubes, etc.) and investigate innovative applications of these materials. Our strengths are in chemical vapor deposition (CVD), Raman spectroscopy, and time-domain terahertz spectroscopy. Current topics of interest include wireless communications and 2D heterostructures.

Course description: This course introduces the properties of electronic materials, with an emphasis on understanding those properties that are important for modern microelectronics. The course begins with a review of concepts from classical physics and quantum mechanics before going on to present essentials of crystal structure, reciprocal space, the free-electron theory of metals, and the band theory of solids. This leads to the introduction of the concept of a semiconductor, followed by carrier statistics, doping, and bandstructure. The course concludes with the theory of optical properties, and some examples of applications of semiconductors to electronic and photonic technologies.
Course description: This course will provide a unified perspective of inorganic/macromolecular and hybrid bonded materials with a focus on quantifying structure-property relationships. This course provides an overview of the role of chemical bonding and electronic structure on defining properties from an electronic structure perspective.
Course description: This course is intended to develop an understanding of the fundamental concepts of electromagnetic fields, with an emphasis on experience for the students in the lab. Topics covered include: electrostatics; magnetostatics; Maxwell's equations; electromagnetic waves in vacuum; plane waves; monochromatic waves; wave polarization; electromagnetic waves at the interface between two media; geometrical optics; guided waves and transmission lines; radiation and antennas; electromagnetic waves in anisotropic, gyrotropic and optically active media.
Course description: The goal of this course is to familiarize students with a variety of materials synthesis and characterization methods that are likely to be useful to (or encountered by) those pursuing experimental research in electrical engineering and/or solid-state materials science. Ideally, students would take this course just before or shortly after undertaking experimental laboratory research, i.e., as a senior undergraduate or first-year grad student.
This course begins with an introduction to various methods commonly used to synthesize metal and semiconductor thin-films. Physical and chemical deposition methods will be the dominant themes here. The focus will then shift to characterization of materials, first by microscopy and then by spectroscopy. Spectroscopic methods discussed will span most of the electromagnetic spectrum.
