In this work, we reported high performance OLED devices with transparent and conductive carbon nanotube anodes after modification. The modifications include IMRE proprietary PEDOT:PSS composite top coating (PSC), concentrated HNO3 acid soaking, polymer encapsulation. For PSC-modified thin film anode, achieved maximum luminescence of ∼9000 cd/m2, close to ITO-based device performance, efficiency ∼10 cd/A, similar device. is approximately 30 450 times better than that for using CNT by others....
The atomic layer deposition (ALD) of Ru using a metal–organic precursor, tricarbonyl(trimethylenemethane)ruthenium [Ru(TMM)(CO)3] and O2 as reactant is reported. high vapor pressure, thermal stability, relatively small ligands the precursor facilitate efficient ALD. Typical self-limiting growth an ALD temperature window 220–260 °C are observed along with significantly per cycle (GPC) (∼1.7 Å) short incubation cycles (∼6) at 220 °C. Density functional theory calculations indicate that rate...
Integration of high-quality ferroelectric thin films, e.g., LiNbO3, in planar device architectures on silicon substrates remains a technological challenge. The successful fabrication suspended micro-disk resonator structure (see figure) suggests that the method reported here—a combination wafer bonding, ion implantation, and layer transfer induced by laser irradiation—may be useful optoelectronic applications.
Growth behaviors of intermetallic compounds (IMCs) and Kirkendall voids in Cu/Sn/Cu microbump were systematically investigated by an in-situ scanning electron microscope observation. Cu–Sn IMC total thickness increased linearly with the square root annealing time for 600 h at 150 °C, which could be separated as first second growth steps. Our results showed that behavior void matched Cu6Sn5, Cu3Sn. It confirmed double-layer kinetics closely related to mechanism microbump, seriously...
Abstract This study investigated the effects of atomic layer deposited (ALD) TiN diffusion barrier and post-annealing on interfacial adhesion energy between ALD Ru SiO 2 films using a four-point bending test. The Ru/SiO structure without was as low 3.20 J/m², it increased to 10.10 J/m² with films. After at 400 °C for 100 h, energies Ru/TiN/SiO structures 7.16 25.26 J/m2, respectively. X-ray photoelectron spectroscopy analysis revealed that thin due formation TiNxOy reaction TiN/SiO...
We have investigated the effect of texture on in-plane (IPP) and out-of plane (OPP) polarizations pulsed-laser-deposited BaTiO3 thin films grown Pt La0.5Sr0.5CoO3 (LSCO) buffered electrodes. The OPP IPP were observed by piezoresponse force microscopy (PFM) for three-dimensional polarization analyses in conjunction with conventional diffraction methods using x-ray reflection high energy electron measurements. electrodes exhibited highly (101) preferred orientation higher component whereas...
