Reducing the mean transverse energy (MTE) of electrons emitted from photocathodes will improve the performance of linear accelerator applications like x-ray free electrons lasers (XFELs) and ultrafast electron diffraction (UED) and microscopy (UEM) e

Owing to the presence of a valley degree of freedom, atomically thin transition metal dichalcogenides show promise for room temperature valleytronic applications. Here, the authors use polarization-resolved Raman spectroscopy to gain insight to the e

We report a lowering of work function for lanthanum hexaboride (LaB6) by monolayer hexagonal boron nitride (hBN) coating. Photoemission electron microcopy (PEEM) and thermionic emission electron microscopy (TEEM) both revealed that the hBN coated reg
