The BCS Energy Gap at High Density. [PDF]

open access: yesJ Stat Phys, 2022
AbstractWe study the BCS energy gap $$\Xi $$ Ξ in the high–density limit and derive an asymptotic formula, which strongly depends on the strength of the interaction potential V on the Fermi surface. In combination with the recent result by one of us (Math. Phys. Anal. Geom.

Graphene antidot nanoribbon tunnel field‐effect transistor

open access: yesMicro & Nano Letters, 2022
A graphene nanoribbon tunnel field‐effect transistor (TFET) model is proposed, in which the antidot pattern is used to generate the heterojunction (HJ) band structure.

Energy-Gap-Refractive Index Relations in Semiconductors—Using Wemple–DiDomenico Model to Unify Moss, Ravindra, and Herve–Vandamme Relationships

open access: yesSolids, 2023
The refractive index of solids gauges their transparency to incident light, while the energy gap determines the threshold for light absorption. This paper provides a mathematical formulation for the relationship between the refractive index and the ...

Energy Gap in Nuclear Matter [PDF]

open access: yesPhysical Review, 1960
The magnitude of the energy gap in nuclear matter associated with a highly correlated ground state of of the type believed to be important in the theory of superconductivity has been evaluated theoretically. The integral equation of Cooper, Mills, and Sessler is linearized and transformed into a form suitable for numerical solution.
