Nonlinear transport properties of a ballistic rectifier fabricated from InAs/AlGaSb heterostructures are reported. The operation of the ballistic rectifier is based on the guidance of carriers by a square anti-dot structure. The structure was defined by electron beam lithography and wet chemical etching. The DC characteristics and magneto-transport properties of the ballistic rectifier have bee...

Assessment of creep damage and residual creep life of a cast HP 40 Nb Mod. Reformer tube was performed, wherein the experimental Larson–Miller diagram and area fraction of creep voids were adopted. The state of damage of the tube in service was metallographically analyzed by using light and electron microscopy. Samples from the serviced reformer furnace tube were cut and prepared for void exami...

FIG. 2. Circuit. The plate supplies of the two tubes are not shown. These come from a single power pack utilizing an Inca C-65 transformer, a 5Y3 tube, two 12 henry chokes, two 4 microfarad condensers, and a 50,000 ohm resistor from which the 250-volt line is taken. The transformer heats the rectifier filament and supplies the heaters of 885 and 6L6 using a separate secondary and resistances of...

A heat-pipe-based multimode thermal rectifier, easily scalable for advanced energy management in industrial applications (e.g., waste heat recovery, solar application and building management), is proposed horizontal transport. The rectifier composed of a copper tube loop having superhydrophilic section superhydrophobic section. rectification effect achieved by the differences sections surface e...

The unimolecular rectifier is a fundamental building block of molecular electronics. Rectification in single molecules can arise from electron transfer between molecular orbitals displaying asymmetric spatial charge distributions, akin to p-n junction diodes in semiconductors. Here we report a novel all-hydrocarbon molecular rectifier consisting of a diamantane-C60 conjugate. By linking both sp...
