AI Article Synopsis
- The study examines the thermoelectric power-factor of Ag-doped rutile-phased TiO thin films at room temperature, focusing on their Seebeck coefficient and electrical conductivity.
- The thin films are composed of two structural variations: a single-layer nanorod and a bilayer of nanorods and nanoflowers, with varying amounts of AgNO.
- Results showed that doping with AgNO significantly improved the thermoelectric power-factor, especially in the bilayer structure, which achieved a threefold increase, leading to enhanced thermoelectric efficiency without altering the overall material structure.
Article Abstract
The thermoelectric power-factor of two types of rutile-phased nanostructured-TiO thin films doped with Ag was investigated at room temperature, by measuring their Seebeck coefficient and electrical conductivity. The thin films, consisting of a nanorod structure (single layer) and nanorod and nanoflower structure (bilayer) of TiO with the addition of different wt.% of AgNO were synthesized on an F:SnO-coated glass substrate. The evaluated thermoelectric power-factor was observed to increase with an increasing wt.% of AgNO for both structures, with the bilayer structure increasing three times more than the undoped bilayer-structure, with a value of 148 μWm-K at 0.15 wt.%. This enhancement was due to the increase in electrical conductivity, which compensated for the small changes in the Seebeck coefficient, which were likely due to the increase in carrier concentration. Consequently, an enhancement in the thermoelectric conversion-efficiency of TiO thin film may be observed by Ag doping, without influencing the layer structure and material phase.

Carbon nanotubes (CNTs) have drawn great attention as promising candidates for realizing next-generation printed thermoelectrics (TEs). However, the dispersion instability and resulting poor printability of CNTs have been major issues for their practical processing and device applications. In this work, we investigated the TE characteristics of water-processable carboxymethyl cellulose (CMC) and single-walled CNT (SWCNT) composite.

ZnSb is widely recognized as a promising thermoelectric material in its bulk form, and a ZnSb bilayer was recently synthesized from the bulk. In this study, we designed a vertical van der Waals heterostructure consisting of a ZnSb bilayer and an h-BN monolayer to investigate its electronic, elastic, transport, and thermoelectric properties. Based on density functional theory, the results show that the formation of this heterostructure significantly enhances electron mobility and reduces the bandgap compared to the ZnSb bilayer, thereby increasing its power factor.

N-type BiTeSe(BTS) is a state-of-the-art thermoelectric material owing to its excellent thermoelectric properties near room temperatures for commercial applications. However, its performance is restricted by its comparatively low figure of merit ZT. Here, it is shown that a 14% increase in power factor (PF) (at 300 K) can be reached through incorporation of inorganic GaAs nanoparticles due to enhanced thermopower originating from the energy-dependent carrier scattering.

A novel additive method to boost the Seebeck coefficient of doped conjugated polymers without a significant loss in electrical conductivity is demonstrated. Perovskite (CsPbBr) quantum dots (QDs) passivated by ligands with long alkyl chains are mixed with a conjugated polymer in a solution phase to form polymer-QD blend films. Solution sequential doping of the blend film with AuCl solution not only doped the conjugated polymer but also decomposed the QDs, resulting in a doped conjugated polymer film embedded with separated ions dissociated from the QDs.
