Abstract

Perovskites have emerged as a rising material category for highly efficient light emission, the electrical control of which is crucial for practical applications. However, achieving efficient, precise, wide-range, and rich control remains challenging due to their inherently poor electrical conductivity. In this work, we demonstrate the integration of two-dimensional (2D) transistors to assist the electrical control of perovskite light-emission. The implementation of a 2D channel with tunable electronic properties and strong interfacial coupling provides an effective bridge between electrical control and light emission of perovskite. The photoluminescence (PL) can be efficiently modulated with a small bias voltage of just 0.2 V, achieving a modulation efficiency of ∼87% per voltage. Furthermore, the PL enhancement can reach up to ∼700% with the assistance of gate voltage. This study underscores the promise of 2D transistors as a low-power, high-efficiency, and highly integrated platform for tailoring the optoelectronic properties of perovskites.

集成到二维晶体管中的钙钛矿发光的电气控制

钙钛矿已成为一种新兴的高效发光材料，其电气控制对实际应用至关重要。然而，由于其固有的导电性差，实现高效、精确、宽范围和丰富的控制仍然具有挑战性。在这项工作中，我们展示了二维（2D）晶体管的集成，以协助钙钛矿发光的电气控制。二维通道的实现具有可调谐的电子特性和强界面耦合，为钙钛矿的电气控制和光发射提供了有效的桥梁。光致发光（PL）可以用仅0.2 V的小偏置电压有效调制，实现每个电压约87%的调制效率。此外，在栅极电压的帮助下，PL增强可以达到~ 700%。这项研究强调了二维晶体管作为一种低功耗、高效率和高度集成的平台的前景，用于定制钙钛矿的光电特性。
