The discovery of Graphene – an atomically thin layer of carbon atoms arranged in a honeycomb lattice – received the 2010 Nobel Prize in Physics for isolating a single atomic layer of this material. The unusual electronic properties of Graphene, spurred the search for other two-dimensional materials. Dr. Humberto Gutierrez, a Tenure-Track Assistant Professor in Physics and Astronomy, is considered a leader in this emerging field of two-dimensional materials. He has done pioneering work in the synthesis and characterizations of a new class of two-dimensional materials called Transition Metal dichalcogenides (TMDs).  When a single layer of this material is isolated from the rest, new physical properties arise, including highly efficient light absorption and emission, making these materials very attractive for utilizing them in the next generation of opto-electronic devices (light emitters, photo-detectors and photovoltaics) that are not only flexible and light-weight but also energy efficient and portable. Dr. Gutierrez’s research focuses on tailoring the physical properties of  these atomically thin TMD based sheets by controlling their chemical composition, electronic doping and strain fields. He is also developing new methods to locally modify the properties of these materials and synthesize in-plane hetero-structures that could eventually lead to a paradigm shift in the fabrication of opto-electronic devices. He is actively collaborating with Professor Jayanthi and the rest of the Condensed Matter Theory group to provide an integrated approach of theory and experiments for a better understanding of the physics underpinning the properties of these 2D materials.
