After Millikan's result, the constants used to determine the parameter A were modified to account for a more accurate representation of the mean free path
by several authors: Langmuir , Davies , DeMarcus and Thomas , Reif , and Fuchs .
Raineri, "Mapping the density of scattering centers limiting the electron mean free path
in graphene," Nano Letters, vol.
where c is Adzumi's constant (0.9 ), [P.sub.p] is pore pressure, and [lambda] is mean free path
where d is the film thickness, [[lambda].sub.0] is the electron mean free path
, and p is the surface scattering factor.
An approximate mean free path
equation for the air molecules is therefore given by (4) and (5).
One of the other values that are calculated in this study of GAGOC and CMO is the mean free path
(MFP) which is described in [15, 16].
"Our work is the first ab initio calculation of the key quantities of interest for hot carriers--lifetime, which tells us how long it takes to lose enera, and the mean free path
, which tells us how far they travel before losing energy."
These electrons travel freely on average by a distance called electron mean free path
equal to l = [[upsilon].sub.F][tau], where [[upsilon].sub.F] is the Fermi velocity.
Abstract: Polymers are usually considered thermal insulators, because the amorphous arrangement of the molecular chains reduces the mean free path
of heat-conducting phonons.
where c, v, and l are the volumetric heat capacity of the medium, speed of sound in the medium, and mean free path
, i.e., the average distance between successive collisions for the heat carrier, respectively.
NIST IMFD database was utilized to find inelastic mean free path
of electrons in solids .
