Abstract

I will report our latest results studying the optoelectronic properties and thermal transport characteristics of nanoscale materials and devices. In particular, we have observe enhanced photoluminescence and photocurrent in monolayer MoS2 under ionic liquid gating conditions due passivation of surface states. The Fabry-Perot resonance in GaAs nanowires can also be significantly enhanced through surface passivation and local field enhancement. In carbon nanotubes pn-junctions, we observe Zener tunneling behavior and photocurrent generation in quasi-metallic nanotubes and non-ideal diode behavior in semiconducting nanotube. Lastly, the thermal interface conductance across a graphene/hexagonal boron nitride heterojunctions. If time permits, I’ll also discuss photocatalytic reduction of CO2 to methanol.

Biography

Prof. Cronin received his Ph.D in physics at MIT in 2002, after working in Professor Mildred Dresselhaus' research group measuring the transport properties of nanowires and quantum well structures. He subsequently conducted his post-doctoral research measuring single molecule optical spectroscopy and electron transport of individual carbon nanotubes at Harvard University with Professor Michael Tinkham.
