Abstract

Beta-phase gallium oxide, β-Ga2O3, in transistors and diodes has been reported due to its distinctive electrical characteristics, such as wide bandgap, low leakage current, and high breakdown electric field. However, besides such conventional basic devices, more advanced device applications using β-Ga2O3 are always necessary. Here, we report on the dynamic behavior of Pt/β-Ga2O3-based Schottky diode for power-efficient organic light emitting display (OLED). Two Schottky diodes are back-to-back connected in series to form a half-wave rectifier circuit and finally integrated with an OLED diode pixel. When AC voltage is applied to the circuit at a frequency greater than 60 Hz, blinking of the OLED light is indistinguishable to human eyes. By way of the rectifier circuit, the OLED pixel efficiently saves more than 35% of the power that should be consumed by applying DC voltage.

实现 60 赫兹半波整流的 Pt/β-Ga2O3 肖特基器件，用于高能效像素显示器

β-氧化镓（β-Ga2O3）具有宽带隙、低漏电流和高击穿电场等独特的电气特性，因此在晶体管和二极管中的应用已有报道。然而，除了这些传统的基本器件外，使用 β-Ga2O3 的更先进器件应用始终是必要的。在此，我们报告了基于 Pt/β-Ga2O3 的肖特基二极管在高能效有机发光显示器（OLED）中的动态行为。两个肖特基二极管背靠背串联形成一个半波整流电路，最后与一个有机发光二极管像素集成在一起。当向电路施加频率大于 60 Hz 的交流电压时，OLED 灯光的闪烁是人眼无法分辨的。通过整流电路，OLED 像素可有效节省 35% 以上的直流电压消耗功率。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
