Circle the appropriate answer, answer the question, or derive the requested result (). In a semiconductor, carrier mobility is a function of all of the following except___. Temperature Doping concentration Electric field Resistivity The bond model and the band model for a semiconductor crystal both describe the same physical structure and electrical properties of the lattice.

Solution

1) in a semiconductor carrier mobility is a function of temperature.

therefore, the correct option is (A).

2) the bond model and the band model for a semiconductor crystal both describe the same physical structure and electrical properties of lattice.

(true)

therefore the corrrect option is (a).
