A Collected Set of Playlists of MIT Videos

Playlists of MIT Videos Collected from YouTube The last posting gave you video playlists from the Khan Academy.  Here’s another one that will increase your higher level of thinking and challenge in pursuing these highly  technical topics. You’re probably aware of Massachusetts Institute of Technology’s  (MIT’s) Open Courseware.  You’ll find here various collections of  video [...] . . . → Read More: A Collected Set of Playlists of MIT Videos

Video Playlists from the Khan Academy

Video Playlists from Khan Academy One of the most valuable resources is from the Khan Academy. For your convenience, I used their playlist from YouTube and are found in the right. Some of the topics is what I plan to do but since Salmon Khan did them, this will save me time to develop other [...] . . . → Read More: Video Playlists from the Khan Academy

Semiconductor Tutorial: Drift and Diffusion Currents

In a semiconductor,  there are holes and electrons being created.   These charged holes and electrons are also known as carriers.   The movement of these carriers  in the semiconductor is due to two processes. Drift Current Density One process concerns drift movement results from an electric field.  The other is known as diffusion resulting from varying [...] . . . → Read More: Semiconductor Tutorial: Drift and Diffusion Currents

Microelectronics Tutorial: Extrinsic Semiconductors

Concentrations of electrons and hole are small found in intrinsic semiconductors. As a result, the currents are small as well. We can increase these concentrations by adding some impurities to the semiconductor crystal. We’d like to have the impurity atom have a different number of valence electron than the semiconductor crystal. Also, we want the [...] . . . → Read More: Microelectronics Tutorial: Extrinsic Semiconductors
