Abstract

This paper presents the implementation of indium gallium arsenide field-effect transistors (InGaAs FETs) as non-volatile memory using lattice-matched II-VI gate insulator and quantum dots of GeOx-cladded Ge as the floating gate. Studies have been done to show the ability of II-VI materials to act as a tunneling gate material for InGaAs based FETs, and GeOx-cladded Ge quantum dots having the ability to store charges in the floating gate of a memory device. Proposed structure of the InGaAs device is presented.
