Freshly cleaved muscovite mica

Figure 8 Atomic force micrograph of a bilayer of barium stearate deposited at 25 mN m on freshly cleaved Muscovite mica (one upstroke and one downstroke) and stored in the subphase for about 30 min before imaging. It appears that elongated patches of the bilayer have detached themselves from the surface and stacked themselves onto the top of undisturbed areas (see also Figure 9).

Table 6.5 Contact angle measurements on a freshly cleaved muscovite mica surface, each having an assumed standard deviation of 0.5. The liquids are DIM = diiodomethane, ABM = a-bromonaphthaiene, FORM = formamide, GLY = glycerol, WATER = water. Prom these angles, surface tension components and parameters (mj/m ) were calculated using all the contact angle data (Set A), without the water contact angle (Set B) and using only the polar liquid contact angles (Set C). The value 0/7 becomes very unreliable when the water contact angle is omitted, while the omission of the apolar liquids introduces a moderate uncertainty in 7. ...

The rubrene source material was purchased from Aldrich (purity > 98%) and purified by threefold sublimation under dynamic vacuum conditions. The rubrene layers were evaporated in a standard HWE reactor on freshly cleaved 2Mi muscovite mica. Two different growth rates were used by employing different... 

In these terms C. Mauguin reported in 1913 the first observation of the orienting action of freshly cleaved surfaces of the muscovite mica on a nematic liquid crystal p-azoxyanisole ...
