Using the thermofield dynamics formalism we study the effect of temperature on supersymmetry within the context of supersymmetric quantum mechanics. The model considered here involves an interaction not of polynomial type and it is shown here that the finite-temperature effect causes spontaneous breaking of supersymmetry.
ABSTRUCTHeavy metal gettering capability on ELTRAN ® was studied by controlling surface treatments for handle wafer prior to wafer bonding. Hydrophobic bonding pre-treatments wafer had much higher heavy metal gettering capability at bonding interface than hydrophilic wafer. In the case of hydrophilic bonding pre-treatments, atomically flat bonding interface was observed by cross-sectional TEM. On the other hand, in the case of hydrophobic bonding pre-treatments, "nano gaps" were observed at bonding interface. We concluded that these differences in the structure at the bonding interface caused the difference in the gettering capability. It is possible to control gettering capability by no additional steps in SOI wafer process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
