Low-resistivity bulk silicon prepared by hot-pressing boron- and phosphorus-hyperdoped silicon nanocrystals

open access: yesAIP Advances, 2014
Technologically important low-resistivity bulk Si has been usually produced by the traditional Czochralski growth method. We now explore a novel method to obtain low-resistivity bulk Si by hot-pressing B- and P-hyperdoped Si nanocrystals (NCs).

Hot carrier solar cells by adiabatic cooling [PDF]

open access: yesarXiv
Hot carrier solar cell is proposed where charge carriers are cooled adiabatically in the charge transport layers adjoining the absorber. The device resembles an ideal thermoelectric converter where thermopower, and therefore also carrier entropy, are maintained constant during cooling from the temperature attained in the absorber to the temperature at ...

Primordial Black Hole Hot Spots and Out-of-Equilibrium Dynamics [PDF]

open access: yesarXiv
When light primordial black holes (PBHs) evaporate in the early Universe, they locally reheat the surrounding plasma, creating hot spots with temperatures that can be significantly higher than the average plasma temperature. In this work, we provide a general framework for calculating the probability that a particle interacting with the Standard Model ...
