The thermoelectric compatibility factor is used to rationally select materials for a segmented thermoelectric generator. The thermoelectric potential is used for the exact analytic expressions for materials with temperature dependent thermoelectric properties. This calculation does not assume constant or averaged thermoelectric properties as is often done for analytic results. The calculations ...

We report on the characteristics of a lab-assembled UV single photon detector based thermoelectrically cooled silicon carbide (4H-SiC) avalanche photodiode (APD). The SiC- APD in this experiment was fabricated with beveled mesa structure, electronics designed to achieve passive Geiger-mode operation and convert signal transistor–transistor logic by readout backend. attached SiC-APD 4-stage ther...

The utilization of portable box coolers (PBC) for traditional fishermen is quite popular in Indonesia. However, pure water's cooling medium still limited to ice. With the development PCM technology, fatty acids began be used. Likewise, use thermoelectric (TEC) directly on PBCs has also been widely developed. In this study, a combination based acids, namely lauric acid, myristic and stearic acid...

Accuracy of the Harman measurement largely depends on the heat transfer between the sample and its surroundings, so-called parasitic thermal effects (PTEs). Similar to the material evaluations, measuring thermoelectric modules (TEMs) is also affected by the PTEs especially when measuring under atmospheric condition. Here, we study the correction methods for the Harman measurements with systemat...

Quantum point contacts are in use as an on-chip capacitative readout for the charge state of quantum dot systems. Here we investigate experimentally the back-action of quantum point contacts (QPCs) on a nearby double quantum dot (DQD). Driving current through a QPC influences the DQD state and leads to a measurable current flow in the DQD circuit with no bias voltage applied. The responsible me...

Thermoelectricity, by converting heat energy directly into useable electricity, offers a promising technology to convert heat from solar energy and to recover waste heat from industrial sectors and automobile exhausts. In recent years, most of the efforts have been done on improving the thermoelectric efficiency using different approaches, that is, nanostructuring, doping, molecular rattling, a...
