Re: why Si?
And I gather all answers about Si:
1. abundant semiconductor (sand)
2. high purity
3. lattice constant
4. SiO2 is a good diffusion shield ???
5. high temperature tolerance
6. allow unidirectional flow of current
7. some related components have a rapid switching action ???
8. Less leakage Current
9. low availability and fabrication cost
10. grows a stable high quality oxide
11. Semiconductor has negitive temparature coefficient ???
12. fabrication process is easy
some I'm still not very clear, like why high purity? due to its crystal structure?
And why material could affect the current follow direction? I just know the ohmic contacts could allow current in both directions.
Im sorry I dont know what the switching action & negitive temparature coefficient are?
And I think I also need to know more about its oxide and other related techniques.
Thanks!!!

actually, the world is going to use PLASTIC instead of SILICON, but giant companies invested a lot in their plants (see the last news in the domain)
i understand ur question was a rhetoric one ?
Maybe my question is a little stupid, but i really wonder to know it well. I hope work in this field in future.
