EAGER: Hot electron devices based on "beyond graphene" materials systems

该计划的目的是探索在MoS 2和相关化合物中使用热载流子传输的新型微波和毫米波器件的可行性。MoS 2的能带结构应该能够使负微分电阻不稳定。由于MoS 2可以廉价地生产在大面积的片材上，这种新技术可能在无线传感生物医学、国土安全和“物联网”应用方面具有关键优势。这是高回报和变革性的，因为如果成功的话，它将使全新一代的分层到散装微波和毫米波“超越石墨烯”源，探测器和传感器成为可能，而成本只是现有组件的一小部分。该项目的智力价值在于理解“超越石墨烯”材料中的热载流子输运，并开发用于光子和电光应用的分层双极器件的新操作原理。该项目的更广泛影响将是理解热载流子和双极“超越石墨烯”纳米结构的新基础物理，能够以现有器件的一小部分成本大规模地开发新型微波和毫米波器件;在实现大规模的传感应用中，在开发用于各种各样的“超越石墨烯”材料的应用的新方法中，在播种“超越石墨烯”的电子产业;在创造新的高科技美国就业机会，并在培训下一代科学家和工程师通过“超越石墨烯”相关的新课程和推广各级-从K到12到研究生教育。

The objective of this program is to explore the feasibility of novel family of microwave and millimeter wave devices using hot carrier transport in MoS2 and related compounds. The band structure of MoS2 has should enable Negative Differential Resistance instability. Since MoS2 can be cheaply produced in large area sheets, this new technology could have key advantages for wireless sensing biomedical, homeland security, and "Internet of Things," applications. It is high-payoff and transformative because, if successful, it will enable a whole new generation of layered-to-bulk microwave and millimeter wave "beyond graphene" sources, detectors, and sensors, at a fraction of the cost of existing components. The intellectual merit of the project is in understanding of hot carrier transport in materials "beyond graphene", and in developing novel principles of operation for layered ambipolar devices for photonic and electro-optic applications.The broader impact of the project will be in gaining understanding of new fundamental physics of hot carrier and ambipolar "beyond graphene" nanostructures, enabling the development of novel microwave and millimeter wave devices on large scale at a fraction of the cost of existing devices; in enabling sensing applications at a large scale, in developing new approaches for applications of a large variety of "beyond graphene" materials, in seeding the "beyond graphene" electronics industry; in creating new high-tech American jobs, and in training the next generation of scientists and engineers through "beyond graphene" related new curriculum and outreach at all levels - from K to 12 to post graduate education.
