crushing of silicon flow diagram


Band diagram ,Because a band diagram shows the changes in the band structure from place to place, the resolution of a band diagram is limited by the Heisenberg uncertainty principle: the band structure relies on momentum, which is only precisely defined for large length scales. For this reason, the band diagram can only accurately depict evolution of band structures over long length scales, and has .

Ohmic contact ,An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage I-V curve as with Ohm& 39;s law.Low resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectifi ion or excess power dissipation due to voltage thresholds.

Gray iron ,Silicon is important for making grey iron as opposed to white cast iron, because silicon is a graphite stabilizing element in cast iron, which means it helps the alloy produce graphite instead of iron carbides; at 3% silicon almost no carbon is held in chemical form as iron carbide. Another factor affecting graphitization is the solidifi ion rate; the slower the rate, the greater the time .
