Bipolar conduction
WebJul 6, 2024 · To further understand the origin of reduction in the thermal conductivity, we first estimated the contribution of bipolar conduction to thermal conductivity from a two-parabolic band model, which is an extension of the single parabolic band model. Thereafter, the contribution of additional point defect scattering caused by Pb substitution (Pb ... WebBipolar transistors are mainly formed of two layers of semiconductor material of the opposite type, connected back to back. The type of impurity added to silicon or germanium decides the polarity when it is formed. NPN Transistor. An NPN transistor is composed of two N type material separated by a thin layer of P type semiconductor material.
