Abstract EN
Monosilane (SiH4) plasma has numerous applications in plasma processing, transport coefficients are better to understanding and modeling of these gas discharge processes.
The electron swarms in a monosilane gas under influence of uniform electric field can be calculated using two term approximation of Boltzmann equation for the range 1 ≤ E / N ≤ 1000 Td (1 Td = 1 x 10-17 V.cm2).
The effective ionization coefficient's (α-η) / N and electron swarm parameters are calculated and compared with experimental and theoretical values of drift velocity, characteristic energy, mean electron energy and ionization coefficient.
The critical field strength (E / N)cr.is calculated from the effective ionization curves.
A set of electron molecule collisions has been assembled for monsilane gas which gave a good fit between the calculated and experimental values over the range of E / N investigated.
The calculated distribution functions (EEDF) are found to be non-Maxwellian, having energy variations which reflect the important electron / molecule energy exchange processes.
In addition, the percentages of energy lost by different types of elastic and inelastic collisions are given as a function of electric field strength E/N.
