Influence of p-isopropenylcalixarenestyrene copolymer buffer layer over Alq3based OLEDs

Investigation on internal electric field distribution of organic light-emitting diodes (OLEDs) with Eu2O3 buffer layer

A novel SiC MESFET with recessed P-Buffer layer

We report, for the first time, a silicon carbide (SiC) based metal semiconductor field effect transistor (MESFET) which has a recessed p-buffer layer into the channel region near the source and a recessed channel into the p-buffer layer region near the drain under the gate. The length and thickness of the channel recess into the p-buffer layer are larger than the pbuffer recess into the channel...

Analytical ETL/EML Layer Investigation of Blue OLEDs

Organic light emitting diodes (OLEDs) based display technologies are getting more and more important for smartphones, laptops and televisions. OLED devices consist of thin organic layer stacks between two electrodes. Located around an emission layer, where the radiative recombination of electrons and holes takes place, are layers for the transport and blocking of charge carriers. Thickness, com...

Second Harmonic Generation Diagnostic of Layer by Layer Deposition from Disperse Red 1–Functionalized Maleic Anhydride Copolymer

Layer-by-layer (LBL) electrostatic assembly of poly-electrolytes is proving to be an increasingly rich and versatile technique for the formation of multilayered thin films with a wide range of electrical, magnetic, and optical properties. In the present work we synthesized a new nonlinear optical (NLO) maleic acid copolymer containing Disperse Red 1 moieties, built-up multilayer assemblies by a...

Influence of the buffer layer properties on the intensity of Raman scattering of graphene

Using a model of oscillating dipoles, we simulate the intensity of the G-band in the Raman signal from structures consisting of graphene, separated by an arbitrary buffer layer from a substrate. It is found that a structure with an optimized buffer layer refractive index and thickness exhibits a Raman signal which is nearly 50 times more intense than that from the same structure with a non-opti...
