Journal ArticleDOI

Phase, morphology and core-level electron spectroscopy of nano-sized La0.65Sr0.35MnO3 powders prepared by solution combustion synthesis

TL;DR: In this paper, the X-ray diffraction patterns of powders calcined at different temperatures were analyzed by Rietveld programme and core level photoelectron spectra of lanthanum, strontium, manganese and oxygen were studied in detail.
Journal ArticleDOI

Multilayer Ge nanocrystals embedded within Al2O3 matrix for high performance floating gate memory devices

TL;DR: In this article, the effect of interface traps on the memory behavior using frequency dependent capacitance-and conductance-voltage measurements has been investigated and an enhanced memory window with superior retention characteristics, owing to the Coulomb blockade effect, was demonstrated.
Journal ArticleDOI

Improvement of efficiency in solar cells based on vertically grown copper phthalocyanine nanorods

TL;DR: In this article, the authors used copper phthalocyanine (CuPc) nanorods as donor and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) as acceptor material.
Journal ArticleDOI

Enhanced mobility PMOSFETs using tensile-strained Si/sub 1-y/C y layers

TL;DR: In this article, carbon incorporation in Si epitaxial layers may be an alternative method to deposit enhanced mobility tensile-strained Si MOSFET channel layers directly on a silicon substrate, thereby eliminating the need to deposit a thick relaxed SiGe buffer layer from which dislocations and other defects can propagate to the channel region.
Journal ArticleDOI

Memory Characteristics of Nickel Nanocrystals with High-k Dielectric Tunneling Barriers

TL;DR: In this paper, structural and electrical properties of Ni nanocrystals embedded in high-k HfO 2 have been studied using high-resolution transmission electron microscopy, which revealed the formation of tiny Ni nanoparticles in the average diameter of ∼ 8 nm size for the sample annealed at 1000°C for 5 min.
