Now consider the electron in a material with a gap of 5 eV. Because of the gap, in order to increase the electron's momentum, the electric field must increase the electron's energy by 5 eV, which is impossible without applying ultraviolet light. In this case, what is the electron's velocity after 10-5 s in the electric field? https://www.bartleby.com/questions-and-answers/consider-an-electron-with-initial-velocity-1-ms-in-the-x-direction.-we-turn-on-an-electric-field-of-/e8d9dafc-d854-4bd1-9133-eda651d0c30a
