“holes,” in the valence band can be moved through the solid with externally applied electric fields, collected onto a metal electrode, and sensed as a photoinduced current. Microfabrication techniques developed for the integrated-circuit semiconductor industry are used to construct large arrays of ...
There are various possibilities: in-house R & D in the company laboratories, externally contracted R & D, and joint R & D. In-house R & D commands a strategic advantage, since the company is the sole owner of the technology and can protect it from unauthorized uses. In addition, since...
