The Low Dimensional Structures and Devices group is based at the University of Sheffield, in the UK. The group carries out leading-edge research in the physics and applications of semiconductor nanostructures, with particular emphasis on novel opto-electronic phenomena.
In this channel we will be sharing videos and animations describing some of the science behind our research.
So it sounds like the moiré pattern creates areas of high resistance and low resistance, and replaces the josephson junction is regular superconductors?
This video is incredible, it manages to communicate the basic knowledge and ideas and the animation is so pleasurable to see. Congratulations and thank you!
tbh I found the "glitchy" design a little annoying, but ultimately this video managed to make me understand polaritons. I have read many other sources on the matter and didnt understand it, but this video of all things was the source that did it. So great job 👍
We use the rich toolkit of the semiconductor industry. For instance, we don't need to mechanically twist anything, we can grow the single layer crystals in place through CVD (chemical vapor deposition). This process grows a structure from a series of strategically placed "nucleation" sites by having atoms fall into place from a gas phase. We can then first grow the bottom layer and then change the gas flow conditions, shifting the place where the second lattice will nucleate. This will grow a second rotated layer.
@@alexanderitartakovskii7202 yes but this means absolute fidelity and consistency in fabrication so you can alter these at creation by these small scales and ensure it all fits properly. this stuff requires precision at least for now.
