Enhancement of optical and structural quality of semipolar (11(2)over-bar2) gan by introducing nanoporous sinx interlayers
(Spie-Int Soc Optical Engineering, 2015)Enhancement of optical and structural quality of semipolar (11 (2) over bar2) GaN grown by metal-organic chemical vapor deposition on planar m-sapphire substrates was achieved by using an in situ epitaxial lateral overgrowth ... -
Generalizations of Fibonacci and Lucas sequences
(2002)In this paper, we consider the Hecke groups H(√q), q ≥ 5 prime number, and we find an interesting number sequence which is denoted by dn. For q = 5, we get d2n = L2n+1 and d2n+1 = √5F2n+2 where L2n+1 is (2n + 1)th Lucas ... -
Indium-incorporation efficiency in semipolar (11(2)over-bar2) oriented ingan-based light emitting diodes
(Spie-Int Soc Optical Engineering, 2015)Reduced electric field in semipolar (11 (2) over bar2) GaN/InGaN heterostructures makes this orientation attractive for high efficiency light emitting diodes. In this work, we investigated indium incorporation in semipolar ... -
Comparison of soil fungi flora in burnt and unburnt forest soils in the vicinity of Kargıcak (Alanya, Turkey)
(2002)Out of the 50 soil samples taken from burnt forest land in the vicinity of the village of Kargicak in Alanya and from the adjacent normal forest soils by the Soil Dilution Plate Method 84 different species and 12 sterile ... -
Comparative morphological, anatomical, ecological and chemical studies on endemic Satureja parnassica subsp. sipylea from Turkey
(2002)Satureja parnassica Heldr.et Sart. subsp. sipylea P.H. Davis is a subspecies endemic to Turkey. The anatomical, morphological, ecological and chemical features of S. parnassica subsp. sipylea have been investigated. Plant ... -
Active region dimensionality and quantum efficiencies of ingan leds from temperature dependent photoluminescence transients
(Spie-Int Soc Optical Engineering, 2015)Temperature dependent recombination dynamics in c-plane InGaN light emitting diodes (LEDs) with different well thicknesses, 1.5, 2, and 3 nm, were investigated to determine the active region dimensionality and its effect ... -
Community structure of macrobenthos of a Southeast Texas Sand-Pit lake related to water temperature, pH and dissolved oxygen concentration
(2003)Water temperature (°C), pH, dissolved oxygen concentration (mg/1) and the community structure of the macrobenthos of a small southeast Texas sand-pit (Barry's) lake were studied from June 1995 to February 1996, which covered ... -
Recurrent immersions
(Walter de Gruyter GmbH, 1999)In this paper we consider the relations between immersions of recurrent type with the immersions having certain planar properties. Namely, we investigate the weak recurrent immersions -
Optimisation of the tunable wavelength hot electron light emitter
(1999)We report on the optimization of the hot electron tunable wavelength surface light emitting device developed by us. The device consists of a p-GaAs, and n-Ga1-cursive Greek chi Alcursive Greek chi As heterojunction containing ... -
Nuclear DNA contents of some endemic Hedysarum L. species
(1999)The nuclear DNA contents and nuclear areas of some endemic Hedysarum L. species were investigated. A significant variation in the DNA content of Hedysarum species was established. The 2C nuclear DNA amount in the Hedysarum ... -
Uniform convergence of bieberbach polynomials in closed radon domains
(2003)Recently, the classical Mergelyan's estimation about the uniform convergence of the Bieberbach polynomials to the conformai mapping in a closed domain with a smooth boundary was improved by ourselves. In this study this ... -
