Computing optical properties of ultra-thin crystals
Şahin, Hasan; Torun, Engin; Bacaksız, Cihan; Horzum, Şeyda; Kang, J.; Senger, Ramazan Tuğrul; Peeters, François M. (Wiley, 2016-07)An overview is given of recent advances in experimental and theoretical understanding of optical properties of ultra-thin crystal structures (graphene, phosphorene, silicene, MoS2 , MoSe2 , WS2 , WSe2 , h-AlN, h-BN, ... -
Fundamental mechanisms responsible for the temperature coefficient of resonant frequency in microwave dielectric ceramics
Zhang, Shengke; Şahin, Hasan; Torun, Engin; Peeters, François M.; Martien, Dinesh; DaPron, Tyler; Dilley, Neil; Newman, Nathan (Wiley, 2017-04)The temperature coefficient of resonant frequency (τf) of a microwave resonator is determined by three materials parameters according to the following equation: τf=−(½ τε + ½ τμ + αL), where αL, τε, and τμ are defined as ... -
Mg(OH)2-WS2 van der Waals heterobilayer: Electric field tunable band-gap crossover
Yağmurcukardeş, Mehmet; Torun, Engin; Senger, Ramazan Tuğrul; Peeters, François M.; Şahin, Hasan (American Physical Society, 2016)Magnesium hydroxide [Mg(OH)2] has a layered brucitelike structure in its bulk form and was recently isolated as a new member of two-dimensional monolayer materials. We investigated the electronic and optical properties of ... -
Nitrogenated, phosphorated and arsenicated monolayer holey graphenes
Yağmurcukardeş, Mehmet; Horzum, Şeyda; Torun, Engin; Peeters, François M.; Senger, Ramazan Tuğrul (Royal Society of Chemistry, 2015-12)Motivated by a recent experiment that reported the synthesis of a new 2D material nitrogenated holey graphene (C2N) [Mahmood et al., Nat. Commun., 2015, 6, 6486], the electronic, magnetic, and mechanical properties of ... -
Strong dichroic emission in the pseudo one dimensional material ZrS3
Pant, Anupum; Torun, Engin; Chen, Bin; Bhat, Soumya; Fan, Xi; Wu, Kedi; Wright, David P.; Peeters, François M.; Soignard, Emmanuel; Şahin, Hasan; Tongay, Sefaattin (Royal Society of Chemistry, 2016-09-28)Zirconium trisulphide (ZrS3), a member of the layered transition metal trichalcogenides (TMTCs) family, has been studied by angle-resolved photoluminescence spectroscopy (ARPLS). The synthesized ZrS3 layers possess a pseudo ... -
Tuning the magnetic anisotropy in single-layer crystal structures
Torun, Engin; Şahin, Hasan; Bacaksız, Cihan; Senger, Ramazan Tuǧrul; Peeters, François M. (American Physical Society, 2015-09)The effect of an applied electric field and the effect of charging are investigated on the magnetic anisotropy (MA) of various stable two-dimensional (2D) crystals such as graphene, FeCl2, graphone, fluorographene, and ... -
Unusual lattice vibration characteristics in whiskers of the pseudo-one-dimensional titanium trisulfide TiS3
Wu, Kedi; Torun, Engin; Şahin, Hasan; Chen, Bin; Fan, Xi; Pant, Anupum; Wright, David Parsons; Aoki, Toshihiro; Peeters, François M.; Soignard, Emmanuel; Tongay, Sefaattin (Nature Publishing Group, 2016-09-22)Transition metal trichalcogenides form a class of layered materials with strong in-plane anisotropy. For example, titanium trisulfide (TiS3) whiskers are made out of weakly interacting TiS3 layers, where each layer is made ...
