Structural and Optical Characterization of Ge Nanocrystals Showing Large Nonvolatile Memories in Metal-oxide-semiconductor Structures

Kim, Sung; Choi, Suk Ho; Park, C J; Cho, K H; Cho, H Y; Elliman, Robert


The structural and the optical properties of Ge nanocrystals (NCs) showing large capacitance-voltage hysteresis have been studied by using infrared photoluminescence (PL), high-resolution transmission electron microscopy (HRTEM), high-resolution X-ray diffraction (HRXRD). The memory effect strongly depends on the implant dose, the oxide thickness, and the annealing temperature in metal-oxide-semiconductor devices containing Ge NCs. Well-defined C-V characteristics with large hysteresis are...[Show more]
