Fig. 4From: Enhanced non-volatile memory characteristics with quattro-layer graphene nanoplatelets vs. 2.85-nm Si nanoparticles with asymmetric Al2O3/HfO2 tunnel oxideEnergy band diagram of the memory a with graphene nanoplatelets and b with Si nanoparticles. The energy band diagram of the memory with Si nanoparticles takes into consideration the changes due to quantization and coulomb charging energy of the 2.85 nm Si nanoparticlesBack to article page
