Wide bandgap light emitting materials and devices( Book )

3 editions published in 2007 in English and held by 13 WorldCat member libraries worldwide

Wide bandgap light emitters include laser diodes and light-emitting diodes (LED), the most modern diodes widely used in current technologies as microelectronics and optoelectronics. Rapid advances have been made during the last few years, with the result that more research is devoted to applications in line with the expanding market for optoelectronics. This volume deals with recent research results on wide bandgap light emitting materials, introducing new concepts for devices based on these materials. The editors, scientists with the best reputations, have invited authors from different insti

Research and Development of Low-Light-Level/Near IR Camera Tube with Solid-State Array Target( Book )

2 editions published between 1969 and 1970 in English and held by 2 WorldCat member libraries worldwide

A program was initiated for the research and development of a low-light-level/near infrared TV camera tube with a solid state array target. The first quarter effort was divided into two major tasks: (1) a literature study and critical evaluation of feasible target structures, and (2) the fabrication and delivery of a best effort Si-vidicon camera tube based on previous work. A number of diode type target structures were considered, viz., Ge homojunctions; Ge-GaAs and Ge-Si heterojunctions; active Ge homojunctions with a passive GaAs image face. The main emphasis of the study was placed on conversion efficiency, extension of spectral response, and dark current. Relevant performance capabilities of both homojunction and heterojunction diode arrays are discussed. On the basis of these results, it is planned to emphasize work on the Ge array, possibly with a passive GaAs layer, and on the Ge-Si heterojunction structures. During this period, an Si-vidicon tube was delivered and experimental equipment set up for target evaluation. (Author)
