Effect of QW growth temperature on the optical properties of blue and green InGaN/GaN QW structures

14.04.2016 | Simon Hammersley, Menno J. Kappers, Fabien C.‐P. Massabuau, Suman‐Lata Sahonta, Phil Dawson, Rachel A. Oliver, Colin ..., physica status solidi (c), 2016

Abstract In this paper we report on the impact that the quantum well growth temperature has on the internal quantum efficiency and carrier recombination dynamics of two sets of InGaN/GaN multiple quantum well samples, designed to emit at 460 and 530 nm, in which the indium content of the ...

Structural properties and vertical transport in ZnSe/CdSe superlattices grown on an In0.3Ga0.7As metamorphic buffer layer

16.03.2016 | E. A. Evropeytsev, S. V. Sorokin, G. V. Klimko, S. V. Gronin, I. V. Sedova, K. G. Belyaev, S. V. Ivanov, G. Pozina, ..., physica status solidi (c), 2016

Abstract We report on the growth by molecular‐beam epitaxy of short‐period ZnSe/CdSe superlattices (SLs) on an In0.3Ga0.7As metamorphic buffer layer. Such SLs are considered as a promising material for a wide band‐gap photoactive p‐n junction in a hybrid monolithic ...

Effect of Al doping in the Ag layer of MgZnO/Ag/MgZnO dielectric/metal/dielectric UV–visible transparent conductive films

16.03.2016 | Yukiko Sugimoto, Kanae Igarashi, Shinya Shirasaki, Akihiko Kikuchi, physica status solidi (c), 2016

Abstract Transparent conductive films (TCFs) with dielectric/metal/dielectric (DMD) structure covering the UVA (λ = 315–380 nm) and visible wavelength region (380–780 nm) were fabricated using Al‐doped Mg0.4Zn0.6O (AMZO) dielectric and 1.7 at% Al‐doped Ag (Ag(Al)) metal layers. The ...

Theoretical investigation of the stability of defect complexes in silicon

16.03.2016 | Karine Abgaryan, Ilya Mutigullin, physica status solidi (c), 2016

Abstract In this work theoretical investigation of the stability of various defect complexes including vacancies, self‐interstitials and their clusters was performed by means of ab initio as well as molecular dynamic calculations. Meta‐stable defect configurations similar to those observed ...

Optimisation and design of PV modules for the application on bus roof‐top and system integration for solar cooling

16.03.2016 | Olgu Demircioğlu, Fırat Es, Emine Hande Çiftpınar, Akın Zeybek, Cahit Tuncer, Raşit Turan, physica status solidi (c), 2016

Abstract In this study, an external electrical cooling unit powered by PV modules was installed on the roof‐top of a bus to keep cooled interior atmosphere at a certain temperature level during the journey breaks. All solar cells used in this project were fabricated by Center for Solar Energy ...

Growth, structural and optical properties of ZnO/ZnMgO core‐shell heterostructures

03.03.2016 | S. A. Said Hassani, C. Sartel, C. Vilar, G. Amiri, A. Lusson, V. Sallet, P. Galtier, physica status solidi (c), 2016

Abstract ZnO nanowires have been grown by metalorganic chemical vapor deposition on sapphire substrates. The use of N2O and DEZn as oxygen and zinc precursors combined with high temperature leads to the spontaneous growth of vertical ZnO nanowires (NWs) on underlying three dimensional islands ...

Dislocations in MCT heteroepitaxial structures on (013) substrates and possibilities of dislocation density reducing

03.03.2016 | Yury Sidorov, Ivan Loshkarev, Irina Sabinina, Evgeny Trukhanov, Vasily Varavin, Maksim Yakushev, Aleksei Kolesnikov, physica status solidi (c), 2016

Abstract Dislocations in heterostructures CdTe/ZnTe/GaAs(013) and CdTe/ZnTe/Si(013) were investigated using selective etching and transmission electron microscopy. The calculations of critical film thickness hc were fulfilled for 12 various slip systems, the experimental results were obtained ...

The local electron interaction with crystal defects in wurtzite CdS

03.03.2016 | Orest Malyk, Volodymyr Rodych, Hryhoriy Il'Chuk, physica status solidi (c), 2016

Abstract In the present paper the interaction of electrons with different types of defects with the potential of the limited action radius – polar and nonpolar optical phonons, piezoelectric and acoustic phonons, static strain centers, ionized and neutral impurities – in cadmium sulfide is ...

Towards industrialisation of GaN‐on‐Si based high brightness blue LEDs

25.02.2016 | Liyang Zhang, Wei Sin Tan, Simon Westwater, Antoine Pujol, Andrea Pinos, Samir Mezouari, Kevin Stribley, John Whitem ..., physica status solidi (c), 2016

Abstract The manufacturability of blue LED structures grown on 6‐inch Si (111) substrates is reported. The totally epi‐structure thickness is only 3.75 μm, which allows faster epitaxy process throughput and lower manufacturing costs. Well controlled strain engineering leads to a room ...
