Especially, nanoparticles show ferromagnetic properties at room temperature. In this paper, Ti-doped effects on GaN were deposited on glass and Polyethylene terephthalate (PET) substrates by thermionic vacuum arc and their room temperature magnetic properties are presented for the first time. The structure of the Ti-doped GaN was crystallized in a novel form, nano honeycomb formation. Optical and surface properties of the nano honeycombs and honeycomb nanosheets were determined. GaN and TiN phases were detected in X-ray diffraction patterns. Field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) device were used for imaging of the crystal structure. According to FESEM images, hexagonal crystal formations were detected for all samples. Crystal formations are very good oriented on PET substrates materials according to glass samples. The band gap value of the sample is changed by crystallization dimension. It was found that increasing crystallizations and decreasing crystal dimensions were increased the band gap of the Ti-doped GaN approximately 50 meV. Fourier transform infrared spectra and a vibrating sample magnetometer results were presented. These results confirm the Ti doped GaN honeycomb nanosheets and nano honeycombs show the room temperature ferromagnetic properties. © 2017, © 2017 Taylor & Francis.eninfo:eu-repo/semantics/closedAccessCrystal dimensionsoptical propertiessurface propertiesTi doped GaNAtomic force microscopyCrystal atomic structureEnergy gapFerromagnetic materialsFerromagnetismField emission microscopesGlassHoneycomb structuresIII-V semiconductorsMagnetic propertiesNanosheetsOptical propertiesPlastic bottlesScanning electron microscopySurface propertiesVacuum applicationsVacuum technologyX ray diffractionCrystal dimensionsField emission scanning electron microscopyFourier transform infrared spectraPolyethylene terephthalates (PET)Room temperature ferromagnetismThermionic vacuum arc methodsTi dopedVibrating sample magnetometerGallium nitrideCrystal dimensionsoptical propertiessurface propertiesTi doped GaNAtomic force microscopyCrystal atomic structureEnergy gapFerromagnetic materialsFerromagnetismField emission microscopesGlassHoneycomb structuresIII-V semiconductorsMagnetic propertiesNanosheetsOptical propertiesPlastic bottlesScanning electron microscopySurface propertiesVacuum applicationsVacuum technologyX ray diffractionCrystal dimensionsField emission scanning electron microscopyFourier transform infrared spectraPolyethylene terephthalates (PET)Room temperature ferromagnetismThermionic vacuum arc methodsTi dopedVibrating sample magnetometerGallium nitrideArticle37333333810.1080/02726351.2017.13687532-s2.0-85040982510Q3WOS:000463816100008Q3
