New junctionless RADFET dosimeter design for low‐cost radiation monitoring applications

Abstract: This paper is devoted to the presentation of a quantitative analysis of the Junctionless Gate All Around RADFET (JL GAA RADFET) dosimeter, where the numerical simulation has been carried out using the Atlas 3‐D simulator. The impact of the total dose, alternative gate materials and the channel doping on the threshold voltage of the JL GAA RADFET is addressed. The obtained results have indicated a significant improvement in the subthreshold parameters when compared to the conventional GAA RADFET dosimeter. Ther… Show more

“…Differ from traditional PMOS radiation sensing field effect transistor (RADFET) and some other direct ion storage dosimeter, dual-dielectric gate all around RADFET and junctionless gate all around RADFET [6]- [9], these devices normally consist two polysilicon layers, one of which named floating gate is used to store charge and is electrically isolated. The other one is divided into a large control gate section and a small injector gate section.…”

“…В настоящее время, с развитием новых технологий, проводятся исследования как по совершенствованию традиционных металл-ок-сид-полупроводниковых (МОП или MOS) ра-диационно-чувствительных ПТ (RADFET) [3][4][5], так и по созданию новых специальных конструкций, таких как с плавающим затвором МОППТ (FG-MOS) [6], или ультрасовремен-ных на основе наноструктур беспереходных с окольцовывающим затвором радиочувстви-тельных ПТ (JL GAA RADFET) [7]. Однако та-кие детекторы радиации весьма дорогостоящи, сложны в изготовлении и требуют дополни-тельных, подверженных радиационным изме-нениям вспомогательных элементов, посколь- …”
