Convert from rate to flux for different materials. (f.u. == formula unit)
| Material | Rate (Å/sec) |
| Å/s |
| Material | Material Flux (f.u./cm^2 sec) | Density (g/cc) | Molecular Weight (g/mol) |
|---|---|---|---|
Convert from flux to rate for different materials.
| Material | Flux (f.u./cm^2 sec) |
| #/cm^2 sec |
| Material | Rate (Å/sec) | Density (g/cc) | Molecular Weight (g/mol) |
|---|---|---|---|
Manually enter values to determine rates and fluxes
| Density | Molecular Weight | Rate | Flux |
| g/cm3 | g/mol | Å/sec | #/cm^2 sec |
Use for gas sources [Ref1]
| sscm | flux |
| sscm | #/sec |
Gas flux using the Langmuir equation
H2S rate = 3.54e20*P[torr] /(s*cm^2)
H2Se = rate 2.29e20*P[torr]/(s*cm^2)
Calculate stoichiometric rates for a fixed flux
Fixed Flux f.u./cm^2 sec
| Material | Stoichiometric ratio | Rate (Å/sec) | Density (g/cc) | Molecular Weight (g/mol) |
