First-principles calculation of hot carriers in black phosphorus
(IOP Publishing, 2020-06-26)
Acceso abierto
ABSTRACT
Black Phosphorus (BP), a layered semiconductor, has atracted enormous attention due to its singular anisotropic electronic, optical and thickness-dependent direct bandgap properties. As a consequence, BP has been ...
Radial pulsation of a compact object in d dimensions
(IOP Publishing, 2020-06-26)
Acceso abierto
RESUMEN
The influence of the extra dimensions on the equilibrium and radial pulsation of a compact object is investigated. For such purpose, we solve the stellar structure equations and radial pulsation equations, both ...
