Meenakshi Upadhyaya

MeenakshiPh.D. student 2014-current

Research: thermal transport in disordered semiconductor and organic systems. 

Discoveries: phonon transport in Si-Ge alloy nanowires is superdiffusive, causing the thermal conductivity to increase with the cube root of the nanowire’s length. 

 

Arnab K. Majee

ArnabM.S. 2014-2016, Ph.D. 2016-current

Research: thermal and electronic transport in 2-d materials, including graphene and transition metal dichalcogenides (TMDCs) such as MoS2.

Discoveries: thermal conductivity in graphene nanoribbons diverges logarithmically with length up to 10 microns in length. Grain boundaries in MoS2 do not contribute significantly to electrical resistance, so polycrystalline MoS2 has nearly the same electrical conductivity as single-crystalline MoS2!

Adithya Kommini

Adithya_KomminiM.S. 2014-2016, Ph.D. Student 2016-current

Research: electronic transport and thermoelectricity in semiconductor nanostructures using the Wigner formalism.

Discoveries: quantum effects in semiconductor nanostructures can enhance the Seebeck coefficient.

 

Cameron Foss

Blue Waters UPEP intern 2014-2015, M.S. student 2015-current

Research: first principles methods for the calculation of phonon properties, including dispersion and phonon-phonon coupling. Their application to thermal properties of nanomembranes and 2-d materials under strain and across material heterointerfaces.

Discoveries: thermal conductivity in Si and Ge nanomembranes is anisotropic and thickness dependent. Cross-plane thermal conductivity is highly sensitive to strain, with compressive (tensile) strain increasing (decreasing) the conductivity across the membrane, while leaving the in-plane direction unchanged, thus boosting anisotropy.

Research: thermoelectric properties of group IV alloys containing Sn (Si-Sn, Ge-Sn).
