Electron-Phonon Scattering Rates in 2‐D Polar Metal Heterostructures highlight slide

What Has Been Achieved: These studies provided insights into electronic carrier dynamics in 2-D crystalline elemental metals, including resolving contributions from specific components of a 2-D metal-containing heterojunction.


Importance of the Achievement: This is foundational work towards the eventual application of 2D metals in the optical domain, by revealing how the energy of excited electrons flows through the system and is affected by disorder in the metal.


Unique Feature(s) of the MRSEC/PREM that Enabled this Achievement: Close integration of synthesis and measurement, using measurement modalities that are made possible by the pronounced air stability of the 2D polar metals.
