A detour transition between thermal field emission and space charge limited regimes

C Lin, J Chen, Y Fu - Applied Physics Letters, 2024 - pubs.aip.org
Child–Langmuir law theoretically predicts the transition from thermionic electron emission to
space charge limited (SCL) current density across a diode gap. In this work, we reveal a …

Collisional space-charge-limited current with monoenergetic velocity: From Child–Langmuir to Mott–Gurney

LI Breen, AL Garner - Physics of Plasmas, 2024 - pubs.aip.org
All theories coupling electron emission theories ultimately approach the space-charge-
limited current (SCLC) in vacuum, given by the Child–Langmuir (CL) law, for sufficiently high …

The transition from field emission to collisional space-charge limited current with nonzero initial velocity

LI Breen, AM Loveless, AM Darr, KL Cartwright… - Scientific Reports, 2023 - nature.com
Multiple electron emission mechanisms often contribute in electron devices, motivating
theoretical studies characterizing the transitions between them. Previous studies unified …
