摘要: The effect of tunnel layer thicknesses on the charging/discharging mechanism and data retention Si nanocrystal dot floating gate devices was studied. Floating memories nanocrystals dots with three different SiO2 were fabricated, key variable being oxide thickness. Other parameters which can affect memory properties carefully controlled. electron discharging is discussed based differences in Direct tunneling found to predominate cases 3- 5-nm-thick layers. However, Fowler-Nordheim affects characteristics thicker Clear peak could be observed capacitance-voltage measurements metal-oxide semiconductors nanodot devices. Memory also depended strongly
