High optical transmittance
Wide optical band gap
High electrical conductivity
Low cost
Non-toxicity
Good stability
Requirement of low temperature
Why is Wide band gap energy good?
It can be a very effective optoelectronic devices
There are many III-V and II-VI compound semiconductors with high bandgaps. The only high bandgap materials in…
group IV are diamond
Pitch black. Dead quiet. Dim faint light appears in the distance, approaching, growing larger. As the light nears, we recognize car headlights. Closer and closer until the car is bearing down upon us with great force. . .
