N-type semiconductors are extrinsic semiconductors that carry more electrons, and are created by doping an intrinsic semiconductor with impurities like phosphorus, antimony or arsenic. The “n” in “n-type” stands for “negative,” referring to the negative charge from the large amount of free ...
In this article, you'll learn what a semiconductor is, how doping works and how a diode can be created using semiconductors. But first, let's take a close look at silicon. Silicon is a very common element -- for example, it is the main element in sand and quartz. If you look "...

This creates an insulating layer in the middle of the diode called the depletion zone. © HowStuffWorks A diode is the simplest sort of semiconductor device. Broadly speaking, a semiconductor is a material with a varying ability to conduct electrical current. Most semiconductors are made of ...
Finally, a very thick silicon dioxide layer is deposited on top of the entire staircase, another pattern is lithographically created for the vias, and holes are etched down to the polysilicon layer. The etch is controlled to remove only the silicon dioxide, so each hole stops when the polysili...
Again, electronic components can be in thru-hole orSMD (Surface Mount Devices or Chips). Soldering Tools and Equipment As explained above, soldering can be done the 3 ways: Wave Soldering: Wave soldering is done for mass production. Equipment and raw materials needed for wave soldering are –...
hole, but the entire semiconductor is still neutral. In this type of P-type semiconductor, holes are the main conduction, holes are majority carriers, and free electrons are minority carriers. The principle of N-type semiconductor formation is similar to that of P-type. Intrinsic semiconductors ...
are semiconductor light sources that combine a P-type semiconductor (larger hole concentration) with an N-type semiconductor (larger electron concentration). Applying a sufficient forward voltage will cause the electrons and holes to recombine at the P-N junction, releasing energy in the form of li...

bulk crystals. In particular, it is easier to generate so-called exciton particles: If an electron, known to be negatively charged, is excited in the material by absorbing energy, it is removed from its original position. It leaves behind a mobile charge – a positively charged “hole.” ...
