Dark energy mechanisms in the context of extra dimensional models
Yağmurcukardeş, Mehmet (İzmir Institute of Technology, 2011)Dark energy is the simplest and the most standart explanation to account for the observed accelerated expansion of the universe. In this thesis we use the term 'dark energy' in its standart meaning i.e. a field or fluid ... -
Mechanical properties of monolayer GaS and GaSe crystals
Yağmurcukardeş, Mehmet; Senger, Ramazan Tuğrul; Peeters, François M.; Şahin, Hasan (American Physical Society, 2016-12)The mechanical properties of monolayer GaS and GaSe crystals are investigated in terms of their elastic constants: in-plane stiffness (C), Poisson ratio (ν), and ultimate strength (σU) by means of first-principles calculations. ... -
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 ... -
Pentagonal monolayer crystals of carbon, boron nitride, and silver azide
Yağmurcukardeş, Mehmet; Şahin, Hasan; Kang, J.; Torun, E.; Peeters, François M.; Senger, Ramazan Tuğrul (American Institute of Physics Publishing, 2015-09)In this study, we present a theoretical investigation of structural, electronic, and mechanical properties of pentagonal monolayers of carbon (p-graphene), boron nitride (p-B2N4 and p-B4N2), and silver azide (p-AgN3) by ...
