摘要： The present invention includes a photodiode having a first p-type semiconductor layer and an n-type semiconductor layer coupled by a second p-type semiconductor layer. The second p-type semiconductor layer has graded doping along the path of the carriers. In particular, the doping is concentration graded from a high value near the anode to a lower p concentration towards the cathode. By grading the doping in this way, an increase in absorption is achieved, improving the responsivity of the device. Although this doping increases the capacitance relative to an intrinsic semiconductor of the same thickness, the pseudo electric field that is created by the graded doping gives the electrons a very high velocity which more than compensates for this increased capacitance.

摘要： An apparatus and method of playing an audio quiz game wherein a player attempts to answer a question after listening to a corresponding audio clip provided on a compact disc. Each track of the compact disc contains one or more sound clips separated by audio cues. The questions and answers relating to specific tracks are provided in a book, or playing cards, or in computer memory, and can be randomly accessed.
