Interface‐Driven Thermoelectric Switching Performance of VO + ‐Diffused Soda‐Lime Glass

چکیده
Strongly confined NaVO$^+$ segregation and its thermo-responsive functionality at the interface between simple sputter-deposited amorphous vanadium oxide thin films soda-lime glass was substantiated in present study by in-situ temperature-controlled Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS). The obtained ToF-SIMS depth profiles provided unambiguous evidence for a reversible transformation that caused systematic switching NaVO$^+$/ Na$^+$ Na$^+$/ VO$^+$ intensities upon cycling temperature 25 $^\circ$C 340 $^\circ$C. Subsequently, NaVO complexes were found to be reversibly formed (at 300 $^\circ$C) diffused glass, leading electrical behaviour film system. This new -- diffusion-dependent multifunctionality points towards applications as an advanced material thermo-optical switches, smart windows or thermal sensors.

Coefficient of Performance Optimization of a Single Stage Thermoelectric Cooler
In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, ...
متن کاملNonreciprocal switching of VO(2) thin films on microstructured surfaces.
We demonstrate that the combination of near-field focusing and a switchable oxide layer permits construction of a modulator with different optical switching thresholds in two opposing directions. For that purpose VO(2) layers are deposited onto spherical micrometer-sized particles. The phase transition in VO(2) is induced by a nanosecond-pulsed Nd:YAG laser from two different directions. The me...
متن کاملEnhancement of Robust Tracking Performance via Switching Supervisory Adaptive Control
When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...
متن کاملThermoelectric Effect across the MetalInsulator Domain Walls in VO<sub>2</sub> Microbeams
We report on measurements of Seebeck effect in single-crystal VO2 microbeams across their metal-insulator phase transition. One-dimensionally aligned metal-insulator domain walls were reversibly created and eliminated along single VO2 beams by varying temperature, which allows for accurate extraction of the net contribution to the Seebeck effect from these domain walls. We observed significantl...
متن کاملThermoelectric Performance of Na-Doped GeSe
Recently, hole-doped GeSe materials have been predicted to exhibit extraordinary thermoelectric performance owing largely to extremely low thermal conductivity. However, experimental research on the thermoelectric properties of GeSe has received less attention. Here, we have synthesized polycrystalline Na-doped GeSe compounds, characterized their crystal structure, and measured their thermoelec...
