TL;DR: In this article, the fabrication conditions significantly influence the electron paramagnetic resonance (EPR) and photoluminescence excitation (PLE) spectra obtained, and it is found that green PL emission can be suppressed by coating the nanostructures with a surfactant for all fabrication conditions.
Journal ArticleDOI
Towards the development of flexible non-volatile memories.
TL;DR: The flash memories, resistive random access memories and ferroelectric random access memory/ferroelectric field-effect transistor memories (FeRAM/FeFET) are considered as promising candidates for next generation non-volatile memory device.
Journal ArticleDOI
