I'll give you an specific question.
Can silicon be used instead of carbon? I need an wise explanation.

Any powdered material that is a not too good conductor and doesn't pack too easily. A highly conducting material will have a very low resistance even when the particles are in weak contact, so there won't be much change when they are vibrated. And packing tends to desensitize the material by making it behave more like a single solid object. I'd suggest trying iron filings and maybe let some aluminum filings oxidize a little by soaking in salt water. Of course carbon is easily obtainable; just open up a non-alkaline zinc-carbon battery and take out the center electrode. Or you could try charcoal.

in the family of carbon is silicon and germanium and i forgot the others but they are similar due to the periodic table, check your periodic table.
