摘要: The size of germanium (Ge) nanocrystals in a trilayer metal-insulator-semiconductor memory device was controlled by varying the thickness middle (co-sputtered Ge+SiO2) layer. From analyses using transmission electron microscopy and capacitance–voltage measurements, we deduced that both electrons holes are most likely stored within layer structure rather than at interfaces with oxide matrix.
