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, ...
Hexagonal AlN: Dimensional-crossover-driven band-gap transition

Bacaksız, Cihan; Şahin, Hasan; Özaydın, H. Duygu; Horzum, Şeyda; Senger, Ramazan Tuǧrul; Peeters, François M. (American Physical Society, 2015-02-27)

Motivated by a recent experiment that reported the successful synthesis of hexagonal (h) AlN [Tsipas, Appl. Phys. Lett. 103, 251605 (2013)APPLAB0003-695110.1063/1.4851239], we investigate structural, electronic, and ...
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 ...
Portlandite crystal: Bulk, bilayer, and monolayer structures

Aierken, Y.; Şahin, Hasan; İyikanat, Fadıl; Horzum, Şeyda; Süslü, A.; Chen, B.; Senger, Ramazan Tuǧrul; Tongay, S.; Peeters, François M. (American Physical Society, 2015-06-12)

Ca(OH)2 crystals, well known as portlandite, are grown in layered form, and we found that they can be exfoliated on different substrates. We performed first principles calculations to investigate the structural, electronic, ...
