Electron mobilities in liquid tetramethylsilane at temperatures up to the critical point

Abstract

Electron mobilities have been measured as a function of temperature over the whole liquid range of tetramethylsilane. Above the triple point, the mobility attained a minimum at 260 K and a maximum at 377 K then fell abruptly to a relatively low value near the critical point. This behavior has been shown by rare gas liquids as well as liquid 2,2,dimethylpropane; however, in tetramethylsilane the ratio of maximum to minimium mobilities was much smaller than in any of these other liquids.
