optical properties--->
What is the spectrum of light (range of wavelengths) a semiconductor can absorb (solar cell) or emit (LED).
Band-gap engineering is also possible, in which we alter the band-gap of semiconductor or even have multiple band-gaps in a single piece of semiconductor (this may go beyond the scope of this question, but if you are interested then please let me know).
A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc. – and an insulator, such as glass. Their resistancedecreases as their temperature increases, which is behavior opposite to that of a metal.
