摘要

有效的应变传递是推进二维(2D)材料应变工程及其与柔性器件集成的关键。然而,在弯曲或拉伸过程中,二维材料与其衬底之间通常会发生严重的界面滑移。这种现象不仅降低了应变传递的效率,而且破坏了其可靠性,对二维材料本征应变响应特性的基础研究及其在柔性电子中的实际应用提出了重大挑战。为了解决这个问题,我们提出了一个系统的和优化的退火策略,显着提高了二维材料系统应变传递的有效性和鲁棒性。通过分析不同退火条件下不同柔性衬底上单层硒化钨(WSe2)的应变相关光致发光光谱,确定了衬底的最佳退火温度为玻璃化转变温度。这种退火过程大大增强了二维材料与衬底之间的力学耦合,从而导致更可靠和更大的应变应用。优化后的退火策略使二维材料在柔性基板上的应变传递效率提高了约133.76%。我们的研究结果为二维材料的有效应变调制提供了重要的见解,并为基于二维材料及其异质结构的柔性电子和光电子器件的开发和性能优化提供了有价值的指导。

Enhanced Strain Modulation Efficiency in Two-Dimensional Materials via Optimal Annealing

Enhanced Strain Modulation Efficiency in Two-Dimensional Materials via Optimal Annealing

Effective strain transfer is crucial for advancing strain engineering in two-dimensional (2D) materials and their integration into flexible devices. However, during the bending or stretching processes, severe interfacial slippage commonly occurs between 2D materials and their substrates. This phenomenon not only diminishes the efficiency of strain transfer but also undermines its reliability, posing a substantial challenge to the fundamental study of intrinsic strain response characteristics of 2D materials and their practical implementation in flexible electronics. To address this issue, we present a systematic and optimized annealing strategy that significantly improves the effectiveness and robustness of strain transfer in 2D material-based systems. By analyzing the strain-dependent photoluminescence spectra of monolayer tungsten selenide (WSe2) on various flexible substrates subjected to different annealing conditions, we identified the optimal annealing temperature as the glass transition temperature of the substrate. This annealing process substantially enhances the mechanical coupling between the 2D material and the substrate, leading to more reliable and larger strain application. Optimization of the annealing strategy has resulted in an approximate 133.76% enhancement in the strain transfer efficiency of 2D materials on flexible substrates. Our findings provide critical insights for effective strain modulation in 2D materials and offer valuable guidance for the development and performance optimization of flexible electronic and optoelectronic devices based on 2D materials and their heterostructures.
