Electron-phonon coupling of epigraphene at millikelvin temperatures
Bayan Karimi, Hans He, Yu-Cheng Chang +7
We investigate the basic charge and heat transport properties of charge neutral epigraphene at sub-kelvin temperatures, demonstrating nearly logarithmic dependence of electrical co…

Modification of electron-phonon coupling by micromachining and suspension
Olli-Pentti Saira, Matthew H. Matheny, Libin Wang +2
Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing…

Crossover between electron-phonon and boundary resistance limited thermal relaxation in copper films
L. B. Wang, O. -P. Saira, D. S. Golubev +1
We observe a crossover from electron-phonon (ep) coupling limited energy relaxation to that governed by thermal boundary resistance (pp) in copper films at sub-kelvin temperatures.…
