Resonant X-ray Reflectivity from the Liquid Bi-In Surface
Resonant x-ray reflectivity measurements from the surface of liquid Bi22In78 find only a modest surface Bi enhancement, with 35 at% Bi in the first atomic layer. This is in contrast to the Gibbs adsorption in all liquid alloys studied to date, which show surface segregation of a complete monolayer of the low surface tension component. This suggests that surface adsorption in Bi-In is dominated ...
متن کاملExperimental and theoretical investigation on binary semiconductor clusters of Bi/Si, Bi/Ge, and Bi/Sn.
Bi(m)M(n)- (M = Si, Ge, Sn) binary cluster anions are generated by using laser ablation on mixtures of Bi and M (M = Si, Ge, Sn) samples and studied by reflectron time-of-flight mass spectrometer (RTOF-MS) in the gas phase. Some magic number clusters are present in the mass spectra which indicate that they are in stable structures. For small anions (m + n < or = 6), their structures are investi...
متن کاملBi-partition of shared binary decision diagrams
A shared binary decision diagram (SBDD) represents a multiple-output function, where nodes are shared among outputs. A partitioned SBDD usually consists of two or more SBDDs that often share nodes. The separate SBDDs are optimized independently, often resulting in a reduction in the number of nodes over a single SBDD. We show a method for partitioning a single SBDD into two parts that reduces t...
متن کاملResistance bi-stability in resonant tunneling diode pillar arrays
Resonant tunneling diodes ~RTDs! are one of the most promising quantum effect devices for practical applications. The presence of negative differential resistance at room temperature allows RTDs to be used as memory storage devices. Recent work has demonstrated that the buildup of electron charge in the well can have a strong influence on the bias required to switch between stable states. In ad...
متن کاملOPTICAL PROPERTIES OF CO-EVAPORATED THIN FILMS OF BINARY Bi 0-Te 0 AND Bi 0 -V 0 SYSTEMS
Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...
