项目摘要

The broader impact of this Small Business Innovation Research (SBIR) Phase I project will be the creation of a more efficient power grid by enabling smaller increased efficiency power converter circuits and units. Additionally, more efficient power converters will enable greater efficiency in the manufacturing and electric vehicle industries, as well as a more efficient power grid. The proposed project will investigate the use of a pulsed excimer laser annealing (PLA) technique to activate implanted dopants and repair implant induced damage in GaN films grown on GaN substrates for the fabrication of vertically conducting, high voltage field effect transistors. The ultimate goals of this Phase I project are to develop viable prototypes for an enhancement mode vertically conducting field effect transistor using the PLA technique. The key application of these devices will be in switched mode power supplies, which can be made smaller than current state of practice since vertical GaN devices will be associated with smaller parasitics. The development of a scalable prototype vertical gallium nitride (GaN) vertical Field Effect Transistors (FETs) will open a path toward scaled production and commercialization of higher breakdown devices will lead to smaller, more efficient power supplies and converter end products in the power electronics market.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小企业创新研究 (SBIR) 第一阶段项目的更广泛影响将是通过启用更小、效率更高的电源转换器电路和单元来创建更高效的电网。此外，更高效的电源转换器将提高制造和电动汽车行业的效率以及更高效的电网。拟议的项目将研究使用脉冲准分子激光退火（PLA）技术来激活注入的掺杂剂并修复在 GaN 衬底上生长的 GaN 薄膜中注入引起的损伤，以制造垂直导电的高压场效应晶体管。该第一阶段项目的最终目标是使用 PLA 技术开发增强型垂直导电场效应晶体管的可行原型。这些器件的关键应用将是开关模式电源，其尺寸可以比当前的实践状态更小，因为垂直 GaN 器件将具有更小的寄生效应。可扩展原型垂直氮化镓 (GaN) 垂直场效应晶体管 (FET) 的开发将为更高击穿器件的规模化生产和商业化开辟道路，这将导致电力电子市场中更小、更高效的电源和转换器最终产品该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
