Nettet27. apr. 2024 · The hole is therefore locally dressed by the spin background, forming a magnetic polaron with a velocity ultimately determined by J. (b) Left: average of experimental images before hole release for one prepared hole. The apparent additional hole in the upper right is caused by defects in the imaging path. Nettet12. mar. 2024 · In a semiconductor like GaAs, the saturation velocity for both holes and electrons is on the order of 10 7 cm/s. However, under lower electric fields E, the drift velocity of electrons is much larger than that of holes, since v d = μ E, where the mobility μ of electrons is much greater than holes. Why then are the saturation velocities …

NettetWe get R squared is equal to 32,000 divided by 15 rho-- rho is 1,000, so R squared is equal to 32,000 over 15,000, which is the same thing is 32 over 15. R is equal to the square root of 32 over 15, and that's going to be meters cubed per second. I get 32 divided by 15 is equal to 2.1, and the square root of that 1.46.
