From 2D to 1D: Atomically quasi ... Yet, despite the successful transition from 3D to 2D, the barrier separating 2D and 1D has been significantly more challenging to overcome.

Yet, despite the successful transition from 3D to 2D, the barrier separating 2D and 1D has been significantly more challenging to overcome.

They also observed the crossover from 1D Fermi arc edge states to the 2D Fermi arc surface states on ... and (114) have been never investigated. Here is a 3D topographic STM image containing ...

“This is due to the unique 2D quantum confinement inside the 1D nanowire as well as the greatly improved crystal quality.” The research has been published in the peer-reviewed journal Science . Dou ...
