摘要: In this paper, an analytical model has been developed for junctionless silicon on insulator ion-sensitive FET pH sensing applications. The sensors detect the change of hydrogen ion concentration in aqueous solution. modeled results show good agreement with simulation obtained by using Sentaurus. electrolyte region considered changing appropriate intrinsic semiconductor material which electron and hole charges represent mobile ions effect surface potential, threshold voltage, drain current investigated through simulations. addition, impact different gate oxide materials, act as adhesion layer, investigated. response is defined amount voltage shift when (in injected solution) varied from lower to higher values. Effect thickness sensitivity also discussed paper.
