Fusing Light With Heat: Polaritons for Nanoscale Thermal Transport & Sensing
07 Oct 2021   Contributor(s):: Thomas Beechem
Light exhibits a wave nature. Phonons do too. Within the infrared portion of the spectrum, these differing “waves” can interact to form hybrid energy carriers called polaritons. Polaritons, in turn, provide fundamental advantages for optical functionality and...

Solar Ovens: Understanding Energy Transfer
28 Jan 2020   Contributor(s):: Christina LevyssohnSilva, NNCI Nano
At the end of this lesson, students will understand that solar energy radiates from the sun to the Earth and gets trapped within the oven. Students will be able to explain how the thermal energy flows from the hot air to the cold water via conduction and will indicate that this would continue...

Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride
06 Dec 2018   Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan
Graphene is a zerobandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (hBN) opens a bandgap in the band structure of...
