Excitonic emissions of AgInS2 crystals with chalcopyrite and orthorhombic structure
13-05-2013 | Kazuki Wakita, Umihito Miyamoto, Raul Paucar, Kazuhiro Honjo, YongGu Shim, Takahiro Tokuda, Kenji Yoshino, physica status solidi (c), 2013
Abstract Micro‐structure of AgInS2 grown by the hot‐press method has been examined by the properties of free‐exciton emission using a scanning confocal‐microscopy system. The crystal structures are distinguished by a two‐dimensional image of free‐exciton emission at RT. The excitonic ...
Electronic structures of ternary‐layered semiconductor TlGaSe2 investigated by photoemission spectroscopy
13-05-2013 | Satoru Motonami, Kojiro Mimura, YongGu Shim, Kazuki Wakita, Hitoshi Sato, Yuki Utsumi, Shigenori Ueda, Masashi Nakat ..., physica status solidi (c), 2013
Abstract Electronic structures of the ternary‐layered semiconductor TlGaSe2 have been investigated by hard and soft X‐ray photoemission spectroscopies (HAXPES and SXPES). The spectral shape of all core levels obtained from HAXPES and SXPES can be represented by a symmetric Lorentzian, ...
Fabrication of Cu2SnS3 thin films by sulfurization of evaporated Cu‐Sn precursors for solar cells
13-05-2013 | Naoya Aihara, Hideaki Araki, Akiko Takeuchi, Kazuo Jimbo, Hironori Katagiri, physica status solidi (c), 2013
Abstract The ternary compound semiconductor Cu2SnS3 (CTS) is formed from non‐toxic materials that are abundant in Earth's crust and other low‐cost elements. CTS has also been reported to a band gap energy range of 0.93–1.77 eV and an absorption coefficient of 1.0×104 cm–1. Consequently, ...
Crystal structures and band‐gap energies of Cu2Sn(S,Se)3 (0≤ x ≤1.0) solid solution
13-05-2013 | Takeshi Nomura, Tsuyoshi Maeda, Kouji Takei, Masaru Morihama, Takahiro Wada, physica status solidi (c), 2013
Abstract Cu2Sn(S1–xSex)3 (CTSSe) solid solutions with 0 ≤ x ≤ 1.0 were synthesized by mixing the elemental powders and post‐annealing at 600 °C. The crystal structure of Cu2SnS3 (CTS), Cu2SnSe3 (CTSe), and their solid solution were determined by Rietveld refinement of the powder X‐ray ...
Phase transition and Raman‐active modes in TlInS2
13-05-2013 | Raul Paucar, Kazuki Harada, Ryoya Matsumoto, Kazuki Wakita, YongGu Shim, Oktay Alekperov, Nazim Mamedov, physica status solidi (c), 2013
Abstract Raman spectra of layered ternary thallium chalcogenide TlInS2were studied with the aid of 3D confocal Raman system over the temperature range 77–300K in the frequency region of 120–400 cm–1. The observed lines in the obtained Raman spectra were denconvoluted into Lorentzian peaks ...
Optical second harmonic generation in TlMeX2 (Me=In,Ga,X=S,Se,Te)
13-05-2013 | Yoshito Araki, Ryo Asaba, Kazuki Wakita, YongGu Shim, Kojiro Mimura, Nazim Mamedov, physica status solidi (c), 2013
Abstract Optical second harmonic generation (SHG) has been studied in TlMeX2 (Me=In,Ga, X=S,Se,Te) compounds with layered and chain crystalline structures. For layered TlInS2 and TlGaSe2, SHG signal has been observed in a range of temperatures below the point of phase transition into ...
Preparation of CuInS2 thin films from materials grown by mechanochemical method
13-05-2013 | Kanta Sugimoto, Yoji Akaki, Shigeyuki Nakamura, Kenji Yoshino, physica status solidi (c), 2013
Abstract Optical second harmonic generation (SHG) has been studied in TlMeX2 (Me=In,Ga, X=S,Se,Te) compounds with layered and chain crystalline structures. For layered TlInS2 and TlGaSe2, SHG signal has been observed in a range of temperatures below the point of phase transition into ...
In situ ellipsometric study of the three‐stage process in CuInSe2 film deposition
06-05-2013 | Sho Shirakata, Toshihiro Takahashi, Hiroaki Matsunaga, physica status solidi (c), 2013
Abstract In Situ ellipsometric study has been carried out during the deposition of the CuInSe2 thin film by means of the three‐stage process. A rotator analyzing ellipsomerter using a 632.8 nm He‐Ne laser was used. Ellipsometric parameters (Ψ and Δ) and reflectivity R was obtained during ...
Trap levels in CaGa2S4 co‐doped with Eu and rare earth elements
06-05-2013 | Chiharu Hidaka, Takeo Takizawa, physica status solidi (c), 2013
Abstract Long afterglows are observed in the case of co‐doping CaGa2S4 with Eu and one of the other rare earth elements (REEs). Thermoluminescence spectra of these compounds have been measured in order to determine their trap depths. Photoluminescence spectra and decay curves have been ...
Super high sensitive low‐dimensional IR‐detector
06-05-2013 | Huseynov Emil, Ismayilov Namiq, physica status solidi (c), 2013
Abstract The original design of the infrared detector providing ultrahigh parameters of responsivity is proposed. The idea lies in separation of the areas between charge carrier optical generation and formation of electrical signal. The calculations performed for CdxHg1–xTe photodetectors ...
