About Me

I am also known as Jeffrey. I am currently a Ph.D. Student in the Department of Physics at the University at Buffalo of the State University of New York, where I work under the tutelage of Professor Jonathan Bird. I obtained a B.Sc. (Honors) in Physics with a minor in Mathematics from the same university in 2012 with high distinction.

I have wide range of interests in experimental physics, which I am specialized in the study of quantum electronic transport at low temperature. I am primarily interested in magnetoelectric dielectrics and 2D materials for spintronic applications. My current focus is on the electrical characterization of the magnetoelectric chromia, a material that offers a route to virtually zero power consumption and ultrafast switching in post-CMOS spintronic technologies. Major achievements in this work include identifying the key electronic transport mechanisms in chromia, and in evaluating its characteristics as a gate dielectric.

I was also part of the cutting edge resesarch community when I was an undergraduate. I investigated the driving mechanism of the metal insulator phase transition in vanadium oxide bronze.

My major honors/ scholarships include the RISE scholarship from the German Academic Exchange Service, which was awarded in 2011. That gave me an opportunity to work with world renowned scientists at the University of Duisburg-Essen, Germany, on studies of ballistic transport in GaAs/AlGaAs heterostructures. In 2015, I presented my research on chromia in TEHCCON, which led to a best best-in-session award. As of summer 2017, I have co-authored more than 8 peer reviewed publications, including those that are currently under review, and my citation average is 7.75.

Ongoing projects:
Evaluating the electrical properties of Cr2O3 thin films formed on different metallic substrates:
Magnetoelectric (ME) switching in ME chromia requires simultaneous application of magnetic field and electric field. However, current leakage at high electric field (E > 10kV/mm) is significant and this presents a challenging problem, which dielectric breakdown often occurs before the observation of ME switching. We investigate how underlying substrate, where the chromia is grown on, can affect the resulting electrical properties of ME chromia thin films. We found that different substrates lead to the formation of twinning defects in the resulting chromia films. Through proper choice of the substrate, we are able to suppress twinning defects and so to achieve resistivity values in the films that approach those associated with bulk chromia.

Surface magnetization induced spin polarization in 2D materials:
Spin relaxation time in graphene is known to be long (at the order of nanoseconds). Utilizing this property, we hope to spin polarize charge carriers in graphene through the boundary magnetization of the underlying substrate; in other words, spin polarization can be achieved without the need of spin injection. Such technology could open a route to the development of manufacturable, low-power, nonvolatile spintronics devices, capable of operation at or above room temperature.
