Fermi-level tuning to improve the stability of 2D graphene-based FETs

Two-dimensional (2D) semiconductors are a class of semiconducting materials with thicknesses on the atomic scale. These materials have numerous advantageous properties, including good mobilities at thicknesses below 1 nm, ...

Researchers snap first image of an 'electron ice'

More than 90 years ago, physicist Eugene Wigner predicted that at low densities and cold temperatures, electrons that usually zip through materials would freeze into place, forming an electron ice, or what has been dubbed ...
