Photophysics of fullerenes: Thermionic emission [PDF]
AIP Conference Proceedings, 1997 The photoionization of fullerene produced by XeCl pulsed laser is measured as a function of the applied electric field. The intensity of the spectra is attributed to field enhanced thermionic emission. (AIP)

MXenes Contacts for p-type 2D Electronics. [PDF]
Adv Sci (Weinh)Solution‐processed MXene contacts are engineered for p‐type 2H‐MoTe2 transistors. By comparing Ti3C2Tx, Nb2CTx, and Mo2CTx, Nb2CTx is identified as the best‐performing contact among the MXenes examined in this work, offering favorable work‐function alignment, low contact resistance, and near‐ohmic hole injection for scalable 2D electronics.

From molecular autoionization to thermionic emission [PDF]
Molecular Physics, 2007 Autoionization of Rydberg states and delayed ionization are two decay processes where the excess energy in the molecule or cluster is released by ejecting a free electron. While precise spectroscopic studies of molecular autoionization are commonly performed, allowing a very detailed understanding of the ongoing processes, the study of delayed ...

A statistical mechanics derivation of the empirical asymptotic thermionic emission equation
AIP Advances, 2019 This paper will obtain a physical derivation for a very useful empirical emission formula. Thermionic emission has long been understood, by the supply side limited regime, described by Richardson-Dushman’s equation and the space charge regime by Child ...

The thermionic emission constant A [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1929 Abstract 1. Summary of Paper.—The main object of this paper is to apply Nordheim’s theory of the emission coefficient of electrons from metals so as to explain the remarkable relation between the constants A and X of the thermionic emission formula, first recorded by O. W. Richardson and recently reformulated by Du Bridge. This theory
