Amorphous silicon image sensor arrays are being developed for X-ray imaging and document scanning. The arrays have a two-dimensional structure with each pixel containing a sensor and a TFT, both fabricated with a-Si:H by photolithography on 12 × 13″ glass substrates. The design and characteristics of a recent complete X-ray imaging system is described. Measurements show that the sensor can detect...
This work presents, as a function of deposition parameters, the comparative measurements performed on thin magnetic films (0.06-0.6 μm) of Ni 81 Fe 19 and Ni 80 Fe 15 Mo 5 deposited by r.f. plasma sputtering. Magnetic measurements were performed using an alternating-gradient magnetometer. Electrical characterization consisted basically of...
