Resumo(s)
This paper is concerned with summarizing simple analytical models of space-charge sheaths
and tracing their relation to the Child–Langmuir model of an ion sheath. The topics discussed
include the Child–Langmuir law and model of a collisionless ion sheath, the Mott–Gurney law
and model of a collision-dominated ion sheath, the Bohm model of a collisionless ion–electron
sheath, the Su–Lam–Cohen model of a collision-dominated ion–electron sheath, ion sheaths
with arbitrary collisionality, high-accuracy boundary conditions for the Child–Langmuir and
Mott–Gurney models of an ion sheath and the mathematical sense of Child–Langmuir type
models of an ion sheath from the point of view of modern theoretical physics.
