The creation of an electrically polarized layer during the condensation process of polar gases onto a deeply cooled substrate is briefly described. This electret phenomenon can appear in any temperature range where solidification of a gaseous phase on a cold substrate is possible. The magnitude and the sign of the surface charges depend on the condensation temperature only. Also, the stability of...
We have investigated the generation of the elctric polarization in methyl alcohol cryocondensates during deposition of the layer onto a cold substrate of temperature within the range 90–175 K. Interestingly, an electric polarization only appears in the α-phase, below ∼158 K, but none at all in the β-phase above 158 K. We believe that the complete absence of a polarization effect above 158 K is related...
