Coherent control of quantum systems depends on the manipulation of quantum interference
through external fields. In this work, we investigate the effects of DC bias field on coherent …

Optical‐field driven electron tunneling in nanojunctions has made demonstrable progress
toward the development of ultrafast charge transport devices at subfemtosecond time scales …

Refractory materials exhibit high damage tolerance, which is attractive for the creation of
nanoscale field-emission electronics and optoelectronics applications that require operation …

Field emission—the quantum-mechanical tunneling of electrons from the surface of a
material into vacuum by means of a strong electric field—has been studied for over a …

Recent years have seen a surge of interest in nano vacuum channel (NVC) devices due to
their low power requirements, radiation hardness, integrability, and ultrafast switching times …
