Over the past two decades research on wide-bandgap polar AlGaN/GaN heterostructure field effect transistors (HFETs) has resulted in a rapidly growing market in the area of high-frequency/high-power transistors. As the share of this market is inching towards the billion-dollar mark, innovative solutions for improving the transistors’ power-handling/heat-management, and for reliable realization of both enhancement- and depletion-modes of operation (i.e. having a positive and negative threshold-voltage, respectively) are gaining a more prominent status.

在过去的两年里，对宽带隙极性 AlGaN/GaN 异质结构场效应晶体管 (HFET) 的研究导致了高频/高功率晶体管市场的快速增长，该市场的份额为逐步迈向十亿美元大关的创新解决方案，用于改善晶体管的功率处理/热管理，以及可靠地实现增强型和耗尽型操作模式（即具有正和负阈值电压，每个）都获得了更加突出的地位。
