    A Perspective on the State-Of Functionalized 2d Materials
    (American Institute of Physics, 2023) Yağmurcukardeş, Mehmet; Yayak, Yankı Öncü; Aydın, Hasan; Peeters, François M.; Yağmurcukardeş, Mehmet; 04.04. Department of Photonics; 01. Izmir Institute of Technology; 04. Faculty of Science
    Two-dimensional (2D) ultra-thin materials are more crucial than their bulk counterparts for the covalent functionalization of their surface owing to atomic thinness, large surface-to-volume ratio, and high reactivity of surface atoms having unoccupied orbitals. Since the surface of a 2D material is composed of atoms having unoccupied orbitals, covalent functionalization enables one to improve or precisely modify the properties of the ultra-thin materials. Chemical functionalization of 2D materials not only modifies their intrinsic properties but also makes them adapted for nanotechnology applications. Such engineered materials have been used in many different applications with their improved properties. In the present Perspective, we begin with a brief history of functionalization followed by the introduction of functionalized 2D materials. Our Perspective is composed of the following sections: the applications areas of 2D graphene and graphene oxide crystals, transition metal dichalcogenides, and in-plane anisotropic black phosphorus, all of which have been widely used in different nanotechnology applications. Finally, our Perspectives on the future directions of applications of functionalized 2D materials are given. The present Perspective sheds light on the current progress in nanotechnological applications of engineered 2D materials through surface functionalization. © 2023 Author(s).

    Toward Single-Layer Janus Crystals: Off-Balance Materials From Synthesis To Nanotechnology Applications
    (American Institute of Physics, 2021) Yıldız, Ümit Hakan; Şahin, Hasan; Sözen, Yiğit; Özkendir İnanç, Dilce; Yıldız, Ümit Hakan; Şahin, Hasan; 04.01. Department of Chemistry; 01. Izmir Institute of Technology; 04.04. Department of Photonics; 04. Faculty of Science
    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.
