Solar-blind UV detectors with a long wavelength cutoff below 280nm have a board range of applications, from fire detection, flame combustion control, scientific instrumentation and missile detection, to UV astronomy. Traditionally, photomultiplier tubes (PMT) and gas-ionization chambers have been us.....

Thin-film transistors (TFTs) are used in the construction of active-matrix devices like liquid-crystal displays (LCDs), organic light emitting diode (OLED) displays, and image sensors. TFTs based on amorphous silicon suffer from low operating speed and lack of a p-type device, making it difficult to.....

Retardation films or plates have various applications such as polarization manipulation and phase compensation. Half-wave plate (HWP) and quarter-wave plate (QWP) are the most commonly used retardation films. In all applications, the HWP and QWP should work well in the whole visible spectrum (400~70.....
