Lecture 3 Electron and Hole Transport in Semiconductors • Knowing electron and hole densities and mobilities, one can calculate the electrical resistance of semiconductors • n-doping or p-doping can be used to change the conductivity of
Semiclassical model of electron dynamics - ntnu. edu. tw Semiclassical model of electron dynamics How does the electron move in a lattice + weak external field? so that interband transition can be ignored ü Electric field à Bloch oscillation ü Magnetic field à cyclotron motion ü Electric+magnetic field à Hall effect
Chapter 2 Particle Motion in Electric and - MIT OpenCourseWare Particle Motion in Electric and Magnetic Fields Considering E and B to be given, we study the trajectory of particles under the influence of Lorentz force F = q (E + v ∧ B) (2 1) 2 1 Electric Field Alone dv m = qE (2 2) dt Orbit depends only on ratio q m Uniform E ⇒ uniform acceleration In one-dimension z, E z trivial In multiple
Influence of coulomb effects on electron dynamics in . . . In this study, we adjust the field strength ratio to explore how different laser field configurations influence electron dynamics This adjustment impacts the electric field's intensity and orientation, significantly affecting ionization trajectories and the accessible energy states for electrons
