The Question of Thermoelectric Devices Electrical Resistance—A Practical Investigation From a Peltier Effect (Thermoelectric Cooler/Thermoelectric Heater) Perspective

open access: yesHeat Transfer, EarlyView.
ABSTRACT Thermoelectric devices (TEDs) intrinsic electrical resistance is fundamental to its operation. This internal electrical resistance value negatively affects a TED's performance when it is operated as a thermoelectric cooler (TEC), and positively affects a TED when operated as a thermoelectric heater (TEH).

Ferroelectric‐Enhanced Self‐Driven Solar‐Blind Photodetector in the GaN‐In2Se3 p‐n Junction

open access: yesInformation &Functional Materials, EarlyView.
We designed a self‐driven GaN‐In2Se3 p‐n junction photodetector with high performance, leveraging the synergy of the built‐in electric field and ferroelectric polarization. At a bias voltage of 0 V, the photodetector exhibits excellent self‐driven performance in the SBUV region with responsivity of 54.95 mA/W and detectivity of 1.66 × 1012 Jones ...

Core‐shell structure induced surface reconstruction of PbS quantum dots toward high‐detectivity short‐wave infrared photodetectors

open access: yesInfoScience, EarlyView.
We present a core‐shell structure‐induced surface reconstruction treatment for PbS quantum dots (QDs). Highly detective photodetectors and imagers in the short‐wave infrared region are demonstrated based on the surface‐reconstructed QDs with reduced dark current density and improved QD stacking configuration, as shown by grazing‐incidence small‐angle X‐
