Sentences with phrase «electron mobility»
Electron mobility refers to how easily and quickly electrons can move within a material, like a conductor or a semiconductor. It measures their ability to travel in response to an electric field. High electron mobility means that electrons can move quickly, while low electron mobility means they move more slowly. This characteristic is important in determining the efficiency and speed of electronic devices. Full definition
What is meant by electron mobility is the amount of current that can be provided to the LED components.
