Figures

Image of FIG. 1.
FIG. 1.

The threshold external voltage and threshold current for bubble generation in the microvolume glycerin film vs frequency in a system without a coating. The total number of statistical measurements for each tested parameter is 6. Inset: the schematic diagram of the experimental configuration. The left triangular symbols and solid curve represent the variation in threshold external voltage, and the right triangular symbols and dashed curve represent the variation in threshold external electrical current.

FIG. 2.

The threshold external voltage and threshold current for bubble generation in the microvolume glycerin film vs frequency in a system with a coating. The total number of statistical measurements for each tested parameter is 6. Inset: (a) the interference pattern at ac and 50 Hz; (b) the interference pattern at ac and 400 Hz. The thickness of the black dashed arrow in insets indicates the bubble emerging intensity; (c) an equivalent circuit for the coating. Region I is the low frequency region and region II is the high frequency region. The arrows schematically indicate bubbles’ movement. The left triangular symbols and solid curve represent the variation in threshold external voltage, and the right triangular symbols and dashed curve represent the variation in threshold external electrical current.

Image of FIG. 3.
FIG. 3.

Interference patterns of glycerin films at a dc voltage of 98 V for systems (a) without and (b) with a coating. (Two supplemental video files are available in the online edition). The thickness of the black dashed arrow indicates the bubble emerging intensity (enhanced online).; [URL: http://dx.doi.org/10.1063/1.3443633.1] [URL: http://dx.doi.org/10.1063/1.3443633.2]10.1063/1.3443633.110.1063/1.3443633.2
