有意包括整流源极接触的薄膜晶体管对于传感器和驱动器电路具有吸引人的特性：高性能均匀性和几何公差;上级饱和度;以及高固有增益。本文回顾了源极-栅极和多模薄膜晶体管的配置，并提出了他们的超紧凑型传感和数据处理电路的建议应用。具有纳米级隧穿接触的源极栅极晶体管提供了肖特基接触制造路线的替代方案，这带来了加工挑战。新兴的多模态晶体管克服了传统接触控制器件的局限性，并增加了有用的特性：高增益或恒定的设计，在浮栅配置漏极电压变化的免疫力，以及显着更快的响应时间比源极-栅极晶体管。这些器件构成了用于传感、信号调理和信号转换的紧凑型、多功能薄膜电路设计的基础。最后，提出了一个愿景，其中这些电路的属性对于将无缝的用户交互性传达到物理对象至关重要，将它们转换为超越传统显示屏的直观用户界面。
Thin-film transistors deliberately comprising rectifying source contacts have attractive properties for sensor and driver circuits: high performance uniformity and geometrical tolerance; superior saturation; and high intrinsic gain. The paper reviews the source-gated and multimodal thin-film transistor configurations, and presents their proposed applications to ultra-compact sensing and data processing circuits. Source-gated transistors with nanoscale tunneling contacts offer an alternative to the Schottky-contact fabrication route, which presents processing challenges. Emerging multimodal transistors overcome limitations of traditional contact-controlled devices and add to the list of useful properties: high gain or constant transconductance by design; immunity to drain voltage variations in floating gate configuration; and a significantly faster response time than source-gated transistors. These devices form the foundation for the design of compact, yet extremely versatile, thin-film circuits for sensing, signal conditioning and signal conversion. Finally, a vision is presented in which the properties of these circuits will be essential to convey seamless user interactivity to physical objects, transforming them into intuitive user interfaces beyond traditional displays screens.
