Silicon Semiconductor

Animation

Animated rotational perspective of a unit cell of a silicon semiconductor. Electron planes through the lattice carry the conducting current. The electron planes behave as mirror -image negative point charges between two Si+ ions.

Calculated and experimental values for the lattice parameter, cohesive energy, and band gap of crystalline silicon. Calculations are made from exact, closed-form equations containing physical constants only.

	Calc.	Exp.
Lattice Parameter a_l (Å)	5.37409	5.4306 [1]
Cohesive Energy (eV)	2.30204	2.3095 [2]
Band Gap (eV)	1.120	1.12 [3]
