Energy Gap Evaluation in Microcrystalline m-HfO2 Powder
نویسندگان
چکیده
In this paper optical properties of microcrystalline HfO2 powder are investigated. X-ray diffraction and Raman spectroscopy were used to determine that the studied samples in monoclinic phase. Based on analysis diffuse reflectance spectra applying Kubelka-Munk formalism we evaluated indirect bandgap value Eg = 5.34 ± 0.05 eV. The calculated is agreement with independent data for thin films synthesized by various methods. based materials report presented at first Russian scientific confererence participation international community "YENISEI PHOTONICS – 2020"

Band-gap Engineering in Sputter Deposited Amorphous/Microcrystalline ScxGa1-xN
Reactive sputtering was used to grow thin films of ScxGa1-xN with scandium concentrations of 20%70% on quartz substrates at temperatures of 300-675 K. X-ray diffraction (XRD) of the films showed either weak or no structure, suggesting the films are amorphous or microcrystalline. Optical absorption spectra were taken of each sample and the optical band gap was determined. The band gap varied lin...

This paper reports the mechanoluminescence (ML) induced by impulsive excitation of γ irradiated terbium doped KCl single crystals and powder. The KCl crystals having different concentrations of terbium were prepared by melt technique (slow cooling).The crystals of small sizes were cleaved from grown crystal block and crushed to obtain powder or microcrystalline powder. The annealed samples were...

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
15 صفحه اولPairing of cation vacancies and gap-state creation in TiO2 and HfO2
Based on the first-principles calculations, the authors study defect-defect interactions between cation vacancies in rutile TiO2 and monoclinic HfO2. It is found that vacancies are greatly stabilized at small separations because of a large reconstruction of nearby oxygen atoms that have two broken bonds. As a result, O–O bonds resembling O2 or O3 molecules are formed near the divacancy site. Th...
