The X-ray phase contrast imaging using a Talbot–Lau grating interferometer (GI) can
achieve high resolution of low-contrast objects such as soft tissues. The periodic …

A fully vacuum-sealed addressable flat-panel X-ray source based on ZnO nanowire field
emitter arrays (FEAs) was fabricated. The device has a diode structure composed of cathode …

A novel reflective anode flat-panel X-ray source using ZnO nanowire cold cathode and a
metal anode has been developed. Simulation analysis indicated that the reflective anode …

X-ray sources have important applications in medical diagnosis, industrial inspection, etc.
Transparent X-ray source has not been reported before, which enables the applications …

In this paper, we developed a temporal response model of gated ZnO nanowire field emitter
arrays (FEAs) which considers the effects of distributed RC parameters and emission current …
