Abstract:
This
paper
discusses
the
similarities
and
differences
between
two
studies
that
deal
with
resin-coated
field-emission
cathodes.
The two
works
that are
compared
within
this
paper
are
entitled:
Hot
Electron
Emission
from
Composite-Insulator
Micropoint
Cathodes
and
Methods
of
Preparation
and
Characterization
of
Experimental
Field-
Emission
Cathodes.
Within
the
text,
both
studies
are
reviewed
and put
into
context,
pointing
out and
commenting
the
advantageous
features
of this
type of
cathodes.
The
comparison
focuses
mainly
on the
method
of
preparation
including
deposition
of a
thin
film on
the
cathode
tip and
the
characterization
of the
coating
itself.
The
effect
of the
coating
on the
field
emission
is
discussed
as well.
