What Does CPD Stand For?
CPD stands for Contact Potential Difference
CPD, or Contact Potential Difference, refers to the voltage difference that develops between two materials in contact due to the distribution of charge carriers at their interface. This phenomenon occurs as a result of differences in work function between the materials, leading to the formation of an electric field. CPD is crucial in various fields, including materials science, semiconductor technology, and electrochemistry, as it influences electron transfer, surface reactions, and the overall electronic properties of the materials involved.
