Adithya’s work on Winger transport in 2D thermoelectrics published in Phys. Rev. Applied

In this work, we show that the thermoelectric power factor in 2D materials can be dramatically improved by adding periodic potential barriers, such as those depicted schematically in the image above. We find the optimal barrier configuration (height, width, and shape) for transport parallel and perpendicular to the barriers.

Arnab wins Outstanding TA award

Arnab K. Majee was selected as an Outstanding Teaching Assistant for his work with the Spring 2020 offering of ECE244: Modern Physics and Semiconductors for EEs. The award was announced at the annual ECE departmental ceremony, held virtually in May 2020, by the department head C. V. Hollot.

Great work, Arnab!

NETlab receives NSF CDS&E grant

Our lab has been awarded a three-year Computational and Data-enabled Science and Engineering (CDS&E) grant from the National Science Foundation to study thermal transport across interfaces between 2D materials and 3D substrates. Using first-principles methods, we will identify 2D-3D materials pairings that lead to better heat removal, enabling faster and higher-performance 2D nanoelectronics. For more info:

Discovering better 2D thermoelectrics

Here is our newest article, just accepted in the new open-access Journal of Physics: Materials, in which we identify materials properties that will lead to higher thermoelectric power factors in two-dimensional materials. This work will help researchers discover new 2D TEs in the future:

Schematic of the role of inelastic scattering in enhancing thermoelectric properties in 2D materials.

Our work on polymer thermoelectrics published in Nature Communications

Our article on “Tuning charge transport dynamics via clustering of doping in organic semiconductor thin films” has been published in Nature Communications. This was a collaboration with with Dhandapani Venkataraman and my student Meenakshi Upadhyaya on the impact of dopant clustering on the TE performance of polymers. This work was featured in a UMass News article: and several scientific news outlets (EurekaAlert,, Science Daily, etc.)
