Recent advancements in nanofabrication have enabled the creation of vacuum electronic devices with nanoscale free space gaps. These nanoelectronic devices promise the benefits of cold-field emission and transport through free-space, such as high nonl

In this work, we analyze the behavior of planar nano-vacuum channel emitters. We developed a fabrication process to reliably pattern metallic (Au) and refractory (TiN) nanoemitters with sub-10nm features. We then investigated the field emission prope

Samples of a commercial glass fiber FM® (Fiber Max) were used to test the efficacy of a chemical sol-gel surface treatment to enhance their bioactivity. After treatment with tetraethoxysilane (TEOS), individual fiber samples were soaked into a simul

We report on a semiempirical tight-binding model for 3C-SiC including the effect of sp 3 d 5 s* orbitals and spin–orbit coupling (∆). In this work, we illustrate in detail the method to develop such a model for semiconductors with zincblende stru

We demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. Our detector uses field-driven photoemission from resonant nanoantennas to
