Abstract
Manipulating carrier redistribution in piezoelectric semiconductors via piezo- and thermo-photonic effects offering a promising approach for developing tunable optoelectronic devices. In this paper, we present a combined theoretical analysis and photoelectric bridge experiments to characterize and modulate electron transport in a single ZnO nanowire device with two identical electrodes by varying the intensity of ultraviolet light. Additionally, we have developed a comprehensive photo-thermal coupling model that integrates photoexcitation, photothermal and secondary pyroelectric (or thermal strain) effects. This model enables the extraction of carrier concentration and barrier height from the current-voltage curves through parameter inversion. Our findings provide deep insights into the electrical characteristics of nanodevices under bias control and open new avenues for the design of innovative electronic and optoelectronic nanodevices.
期刊介绍:
The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review.
The fundamental subjects considered within the scope of the journal are:
* Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow
* Forced, natural or mixed convection in reactive or non-reactive media
* Single or multi–phase fluid flow with or without phase change
* Near–and far–field radiative heat transfer
* Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...)
* Multiscale modelling
The applied research topics include:
* Heat exchangers, heat pipes, cooling processes
* Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries)
* Nano–and micro–technology for energy, space, biosystems and devices
* Heat transport analysis in advanced systems
* Impact of energy–related processes on environment, and emerging energy systems
The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
