The thermoelectric properties of poly(3,4-ethylenedioxythiophene) (PEDOT)-based materials have attracted attention recently because of their remarkable electrical conductivity, power factor, and figure of merit. In this review, we summarize recent efforts toward improving the thermoelectric properties of PEDOT-based materials. We also discuss thermoelectric measurement techniques and several un...

Thermoelectric energy generators are attractive as potential energy harvesters for converting waste thermal energy into electrical power. Optimized thermoelectric device designs require 100-200 μm element thicknesses currently unachievable with common manufacturing technologies. This work presents both a unique direct-write dispenser printing technique and novel polymer-composite thermoelectric...

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 ...

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...

distribution of water vapor in the atmosphere of the room poultry houses is usually an effective and economical solution to reduce heat stress of the chickens. experimental studies were conducted in a small saloon located in the farm machinery department of shiraz university. the rotary cup fogging system consisted of a cup which was derived by dc motor. rotational speed of the cup caused the w...
