Stability of Oxygenated Groups on Pristine and Defective Diamond Surfaces
Eliezer Oliveira, Chenxi Li, Xiang Zhang +11
The surface functionalization of diamond has been extensively studied through a variety of techniques, such as oxidation. Several oxygen groups have been correspondingly detected o…
Schwarzite and schwarzynes based load-bear resistant radial cellular griding-based 3D printed structures
Eliezer F. Oliveira, Rushikesh S. Ambekar, Douglas S. Galvao +1
Nature-occurring structures exhibiting unique topological features such as complex and gradient porosity has been the basis to create new materials and/or structures. Most studies…
Scalable synthesis of 2D van der Waals superlattices
Michael J. Motala, Xiang Zhang, Pawan Kumar +23
Heterostructure materials form the basis of much of modern electronics, from transistors to lasers and light-emitting diodes. Recent years have seen a renewed focus on creating het…
A Reactive Molecular Dynamics Study of Hydrogenation on Diamond Surfaces
Eliezer F. Oliveira, Mahesh R. Neupane, Chenxi Li +9
Hydrogenated diamond has been regarded as a promising material in electronic device applications, especially in field-effect transistors (FETs). However, the quality of diamond hyd…
Apparent Ferromagnetism in Exfoliated Ultra-thin Pyrite Sheets
Anand B. Puthirath, Aravind Puthirath Balan, Eliezer F. Oliveira +11
Experimental evidence for ferromagnetic ordering in isotropic atomically thin two-dimensional crystals has been missing until a bilayer Cr2Ge2Te6, and a three-atom thick monolayer…
