III-V heterostructure device research for future advanced communications systems is proposed. A two-prong strategy will be pursued. Evolutionary devices with sufficiently well established operating principles on InP are targeted. Considerable technological work is needed before the outstanding electronic properties of InP-based semiconductors is correctly exploited. Our strategy relies on bandgap engineering, careful introduction of strain, and monolayer epitaxial growth. Revolutionary devices will also be investigated with the goal of synthesizing an entirely new class of "smarter" electronic devices with enhanced functionality. To this aim, we are studying quantum effects in reduced dimensionality heterostructures. Our guiding principle is the strong analogy between photons in guided-wave optics and electrons in one-dimensional (1D) quantized structures. Our technological effort will be centered around the fabrication of ballistic quantum wires and coupled quantum wires which are a test-bed for studying new electron interactions in constricted geometries.

提出了未来先进通信系统中III-V异质结器件的研究方向。将采取双管齐下的战略。目标是在InP上具有足够完善的工作原理的进化设备。在正确利用InP基半导体突出的电子特性之前，需要进行大量的技术工作。我们的战略依赖于带隙工程、小心地引入菌株和单层外延生长。革命性的设备也将被研究，目标是合成一种全新的具有增强功能的“更智能”的电子设备。为此，我们正在研究降维异质结构中的量子效应。我们的指导原则是导波光学中的光子与一维(1D)量子化结构中的电子之间的强烈类比。我们的技术努力将集中在弹道量子线和耦合量子线的制造上，这是研究受限几何中新的电子相互作用的试验台。
