The Terahertz Gap: Hidden Frontiers for Materials Chemistry and Physics
Online via Webex
The field of molecular electronics is the study and application of tiny molecular devices that exploit the electronic properties of the molecular orbitals and can be tailored and controlled via the chemical structure and configuration of the molecules.
This talk will present a molecular switch that operates with Terahertz (THz) waves at room temperature. The device consists of a single layer of molecules precisely arranged to show a unique behavior called negative differential conductance. When exposed to THz waves, these molecules can reversibly change their electrical conductance, effectively acting as a switch. This technology has the potential to outperform current THz detectors on the market.
