In this 3rd edition, Professor Dr. M. Omar Faruk contributed a chapter on device physics of solar cells using band models known from studies of Nanostructure Physics or Microelectronics for M.S. students majoring in Physics. We have corrected the lapses in the chapter on device physics of the unijunction transistor. We polished the text of other chapters in places.
