AI Thread Summary
Lattice structure in semiconductors refers to the organized arrangement of atoms that influences electrical properties. In bipolar junction transistors (BJTs), a small current in the base allows for the control of a larger current in the collector due to the transistor's ability to amplify signals. The base current prevents negative charges from accumulating, facilitating the flow of current from the collector to the emitter. This amplification is crucial for various electronic applications. Understanding these concepts is essential for grasping how BJTs function in circuits.

trying to figure out the meaning of lattice struction in semiconductor...
and, why a small current in the base circuit of a transistor can control a large current in collector part when "bipolar junction transmission" happened?
Thanks for any help! :confused:
 
Engineering news on Phys.org
The small current stops negative charge from sitting still on the base ( p part of npn
junction).

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
