    Toward Single-Layer Janus Crystals: Off-Balance Materials From Synthesis To Nanotechnology Applications
    (American Institute of Physics, 2021) Oğuztürk, H. Esra; Sözen, Yiğit; Akyol, Cansu; Özkendir İnanç, Dilce; Yıldız, Ümit Hakan; Şahin, Hasan
    The existence of things is directly related to their structural symmetry in a broad framework ranging from atoms to crystalline materials and from simple cells to complex organisms like humans. However, structural imbalance that occurs through natural or artificial means can provide completely different advantages. Molecules, crystals, and complex structures with structural imbalance constitute the family of Janus-type materials. This perspective provides a comprehensive discussion on the synthesis techniques of Janus-type materials, their use in fields from biology to materials science, and very recent studies on the family of 2D ultrathin graphene-like structures. We believe that, thanks to the advances in experimental techniques, the few-atom-sized off-balanced materials will be indispensable parts of the nanotechnology products that soon will be used in our daily lives.

    Novel Ultra-Thin Two-Dimensional Structures of Strontium Chloride
    (Royal Society of Chemistry, 2020) Akyol, Cansu; Başkurt, Mehmet; Şahin, Hasan
    By performing density functional theory-based calculations, possible stable ultra-thin crystal structures of SrCl(2)are investigated. Phonon calculations reveal that, among the possible crystal structures, three different phases; namely 1H, 1T, and square, are dynamically stable. In addition,ab initiomolecular dynamics calculations show that these three phases are thermally stable up to well above room temperature. Another important stability factor of crystals, the chemical inertness against abundant molecules in the atmosphere, such as N-2, O-2, H2O, and CO2, is also investigated. The analysis shows that SrCl(2)single-layers are chemically stable against these molecules. Moreover, it is determined that in contact with H2O and CO2, ultra-thin SrCl(2)sheets display unique electronic features, allowing them to be used in sensing applications. It is also shown that single layers of SrCl(2)crystals, all having a wide electronic band gap, can form type-I and type-II vertical van der Waals heterostructures with well-known 2D materials such as MoS2, WSe2, and h-BN.
