Two-nanometer laser synthesized Si-nanoparticles for low power memory applications
(Springer International Publishing, 2016)
Current flash memory devices are expected to face two major challenges in the near future: density and voltage scaling. The density of the memory is related to the gate length scaling which is constrained by the gate stack, ...
Enhanced non-volatile memory characteristics with quattro-layer graphene nanoplatelets vs. 2.85-nm Si nanoparticles with asymmetric Al2O3/HfO2 tunnel oxide
(Springer New York LLC, 2015)
In this work, we demonstrate a non-volatile metal-oxide semiconductor (MOS) memory with Quattro-layer graphene
nanoplatelets as charge storage layer with asymmetric Al2O3/HfO2 tunnel oxide and we compare it to the ...
Memory effect by charging of ultra‐small 2‐nm laser‐synthesized solution processable Si‐nanoparticles embedded in Si–Al2O3–SiO2 structure
(Wiley-VCH Verlag, 2015)
A memory structure containing ultra-small 2-nm laser-synthesized silicon nanoparticles is demonstrated. The Si-nanoparticles are embedded between an atomic layer deposited high-κ dielectric Al<inf>2</inf>O<inf>3</inf> layer ...
Charge Trapping Memory with 2.85-nm Si-Nanoparticles Embedded in HfO2

In this work, the effect of embedding 2.85-nm Si-nanoparticles charge trapping layer in between double layers of high-κ Al<inf>2</inf>O<inf>3</inf>/HfO<inf>2</inf> oxides is studied. Using high frequency (1 MHz) ...
Chemically specific dynamic characterization of photovoltaic and photoconductivity effects of surface nanostructures
(American Chemical Society, 2010)
We report characterization of photovoltaic and photoconductivity effects on nanostructured surfaces through light induced changes in the X-ray photoelectron spectra (XPS). The technique combines the chemical specificity ...
Improved efficiency of thin film a-Si:H solar cells with Au nanoparticles
(Institute of Electrical and Electronics Engineers Inc., 2013)
In this work, the effect of Au nanoparticles on the performance of a-Si:H solar cells is investigated experimentally. Au nanoparticles of 10, 20, 50, 80, 100, 200 and 400 nm are spin coated on ITO before metallization. The ...
A plasmonic enhanced photodetector based on silicon nanocrystals obtained through laser ablation
(Institute of Physics Publishing, 2012-10-18)
We present a proof-of-concept photodetector which is sensitive in the visible spectrum. Silicon nanocrystals (Si-NCs) obtained by laser ablation are used as the active absorption region. Si-NC films are formed from a ...
Enhanced light scattering with energy downshifting using 16 nm indium nitride nanoparticles for improved thin-film a-Si N-i-P solar cells
(Electrochemical Society Inc., 2015-05)
In this work the effect of Indium nitride (InN) nanoparticles (NPs) on the performance of a-Si: H solar cells has been investigated. The average J<inf>sc</inf> of InN NPs coated cells was found 6.76 mA/cm2 which is 16.69% ...
Silicon nanoparticle charge trapping memory cell
