The investigations reported in this paper constitute three solutions for enhancement of KTa1-xNbxO3 (KTN) ferroelectric material performances displayed by microwave tunable devices. Quasi-epitaxial KTN films with strongly improved microwave performances...

Field emission electron source with graphene layer
2012 Edition, July 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Field emission electron source can be used in display devices, microwave amplifier, X-ray tubes, and etc. However, the electron beam has to be modulated and focused well in these applications. In this paper, the single layer or double layer grapheme sheet is used...

Microwave based plasma technology
2010 Edition, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Thin film deposition based on plasma CVD processes are well known for many years. While these processes mainly drove the miniaturization of wafer based micro electronics, the upscale was for a long time of minor interest. With the increasing activations in photovoltaic...
