A systematic review of technologies currently under investigation identifies nanocrystalline diamond as the most promising material for miniaturization of transceivers.
Vacuum-UV radiation is useful for surface microanalysis and has enabled development of a new, high-quality chemical vapor-deposition technique operating near room temperature.
Optical electrostriction in microelectromechanical systems enables vibration at 11GHz and allows resonance frequency scaling with wavelength rather than device size.
