Utilizing Azo Photoisomerization To Alter Semiconductor Movie Properties

Generally semiconductor units like transistors have mounted properties, however utilizing an azobenzene (Azo) compound it’s potential to optically alter these properties by exposing them to UV gentle. This is demonstrated in a recent paper by [Jaehoon Ji] et al., as revealed in Science Advances, with accompanying coverage by Princeton University.

Building on earlier analysis on e.g. flakes of MoS₂ with photochromic Azo molecules, a purposeful semiconductor gadget was created. This makes use of a transition metallic dichalcogenide (TMD) monolayer mixed with the Azo compound, with the latter altering {the electrical} and optical properties of the construction.

In each n- and p-type FET semiconductors it was demonstrated utilizing seen and UV gentle that this could alter the service densities within the materials, successfully altering the FET’s conduct.

While that is in fact only a proof of idea, it does present that through the use of (Azo) molecules that may reply to sure electromagnetic radiation frequencies, electrical fields, temperature, and so forth. semiconductor units could be created whose conduct dynamically modifications with these elements. This may doubtlessly present new methods to make programmable circuits and sensors.
