explain the difference of metal, semiconductor, and isolator based on the structure of energy band

Solutions

Expert Solution

Energy gap of solid decide that a matter will behave as conductor, semiconductor and insulator

in metal the band gap is zero so it is good conductor.

in case of semiconductor the band gap is very low so at room temperature is conduct and its conductance increase when temperature increase.

in insulator the gap is high so electron can't reach conduction band, if we increase temperature then the substance get damaged.

Big Band Corporation produces a semiconductor chip used on communications. The direct materials are added at the start of the production process while conversion costs are added uniformly throughout the production process. Big Band had no inventory at the start of June. During the month, it incurred direct materials costs of $935,750 and conversion costs of $4,554,000. Big Band started 475,000 chips and completed 425,000 of them in June. Ending inventory was 50% complete as to conversion costs. Compute (a)...
