BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

Family dinner talks turn into family members scattered throughout the house entranced in their own little electronic world. The over-use of technology is creating an impatient society and it is also diminishing once-valued personal interaction with others. More often now these days‚ people would rather let a machine take a message instead of answering a call;
