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

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.

How does temperature affect the band structure and the I-V characteristics of semiconductor devices? How does changing the carrier lifetime affect semiconductor devices? For a GaAs PN junction, imagine that the device is to be used as a photo-diode. What width of intrinsic layer would you want to design the device with if the photons only absorb in the depletion/intrinsic regions? Assume: wavelength = 0.75um.

Describe how the conductivity of a metal and a semiconductor change with temperature and explain qualitatively why this occurs. Explain how an insulator’s electron energy band structure prevents it from conducting electricity. Diagrams may be useful.

Big Band Corporation produces a semiconductor chip used on communications.

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)...

Explain the difference between array and structure based on their usage in C++ programming. Declare a structure called studentScore which contains name of student, registration number of students, course code and marks. Declare structure variable named studentCS680 based on the structure in (b) to store fifty (50) students’ data. Write a program that prompts a user to enter data for 50 students in a structure variable declared in (b) and calculate the average mark.
