hi
my question is how can understand the topic of semicondutor briefy
first wts i am letion

 

With Google!
Sorta a broad topic to understand and isn't a 1 hr. ordeal. Google around, you will find tons of stuff. Then ask questions on what you read. You will get better answers. Thx l8er

semi-conductors are materials which conduct poorly, but still conduct. As their temperature rises, they conduct better as it causes more electrons to rise into the valence range typically. With normal conductors, i.e. copper, silver, etc, the heat does the opposite.

semi-conductors are typically made impure when used in components. The impurities give the semi-conductor the potential to generate a conductive channel and this is where the transistor fits in.

 

Wikipedia will be good option!
