中文摘要
9526112 MITIN固态毫米波和亚毫米波系统在通信、雷达、诊断和其他领域有着广泛的应用。毫米波系统(频率范围:30-300 GHz)比较发达。由于缺乏合适的亚毫米波辐射源(SRS),亚毫米波(300-3000 GHz)系统距离实际实现还很远。对于受激喇曼散射的理论设计,我们将在非常规区域使用亚微米二极管,即由于瞬时过冲而不是静态负微分电导而导致的电荷积累。初步结果表明,非常规体制器件可以工作在高达500-800 GHz的频率。为了解决这个问题,我们开发了一套复杂的程序,用于数值模拟考虑外部谐振电路的双端器件中的微波发电。其中一个程序包基于使用蒙特卡罗粒子(MCP)技术的外部电路中器件操作的完整动力学描述。第二个程序是基于我们为分析半导体材料和器件中的直流和交流热载流子输运而开发的一种改进的流体动力学方法(MHM)。利用MHM和MCP方法,我们将广泛地研究获得太赫兹波段微波二极管发生器的可能性。***
英文摘要
9526112 Mitin Solid state millimeter and submillimeter wave systems find wide application in communications, radar, diagnostics, and other fields. Millimeter wave system (frequency range: 30-300 Ghz) are relatively well developed. Submillimeter wave (300-3,000 Ghz) systems are still far from practical realization, due to a lack of suitable submillimeter radiation sources (SRS). For the theoretical design of SRS, we will employ submicron diodes in a nonconventional regime, i.e., charge accumulation due to transient overshoot rather than stationary negative differential conductivity. Preliminary results demonstrate that nonconventional regime devices can operate at frequencies as high as 500-800 Ghz. To attack this problem, we have developed a complex of programs for the numerical simulation of microwave power generation in two-terminal devices which account for the external resonant circuit. One package of programs is based on a full kinetic description of device operation in an external circuit using the Monte Carlo particle (MCP) technique. A second package is based on a modified hydrodynamic method (MHM) we have developed for the analysis of dc and ac hot-carrier transport in semiconductor materials and devices. Using MHM and MCP methods, we will extensively investigate the possibility of obtaining microwave diode generators in the terahertz regime. ***
