“…In the recent past, researchers have shown deep interest in experimental evaluation of the performance of several types of electronic equipment; e.g. capacitors [16], Tx lines [17], random-access-memory (RAM) [18], laser [19], photodiodes [20] and PA [21][22][23][24][25] under different environmental conditions. Most of those works are focused on the humidity and temperature effects on the lifetime of devices.…”

“…Двухстороннее δ-легирование позволило повысить кон-центрацию двумерного электронного газа (ДЭГ) до 2 · 10 12 см −2 [2], получение резких и гладких гетеро-границ GaAs/InGaAs квантовой ямы (КЯ) -канала транзистора [3,4], установление оптимального расстоя-ния между δ-слоями и КЯ [5,6], применение составных спейсеров [7,8], использование широкозонных AlAs вста-вок в КЯ [9,10] позволили уверенно получать подвиж-ность электронов свыше 7000 см 2 /В · с при комнатной температуре. Несмотря на все эти значительные усилия, удельная выходная мощность pHEMT -p out долгое время не могла преодолеть порог 1 Вт/мм в частот-ном диапазоне 10−30 ГГц [11][12][13]. Кардинальное увели-чение p out произошло после создания гетероструктур с донорно-акцепторным легированием (donor-acceptor doped pHEMT, DA-pHEMT) [14], которые позволили увеличить p out до 1.7 Вт/мм [15].…”
