Desorption and diffusion energy barriers for CO and CO2 on the proton-disordered and the ordered Fletcher phase of ice Ih.
|Substrate||Adsorbate||Binding sites||E bind a||E diff||D 0||E diff,x||E diff,y||f = Ediff/Ebind|
|ASW (frozen)b||CO (1+3)c||96||147||63||0.032||...||...||0.42|
|ASW (frozen)b||CO (1+6)c||86||134||48||0.009||...||...||0.36|
Notes. The quantities D0 and Ediff are defined in Eq. (2).
Binding energies are time-averaged over the kinetic Monte Carlo runs at temperatures of 25 and 70 K for CO and CO2 .
Amorphous solid water (ASW) values are calculated from simulations published in Karssemeijer et al. (2014b) on substrate . Values are also at T = 25 K.
