    • Direct growth of single-layer terminated vertical graphene array on germanium by plasma enhanced chemical vapor deposition 

      Al-Hagri, Abdulrahman; Li, Ru; Rajput, Nitul S; Lu, Jin-You; Cong, Shan; Sloyan, Karen; Almahri, Mariam Ali; Tamalampudi, Srinivasa Reddy; Chiesa, Matteo; Al Ghaferi, Amal (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)
      Vertically aligned graphene nanosheet arrays (VAGNAs) exhibit large surface area, excellent electron transport properties, outstanding mechanical strength, high chemical stability, and enhanced electrochemical activity, which makes them highly promising for application in supercapacitors, batteries, fuel cell catalysts, etc. It is shown that VAGNAs terminated with a high-quality single-layer graphene ...

    • Revealing the Quasi-Periodic Crystallographic Structure of Self-Assembled SnTiS3 Misfit Compound 

      Rajput, Nitul S.; Baik, Hionsuck; Lu, Jin-You; Tamalampudi, Srinivasa Reddy; Sankar, Raman; Al Ghaferi, Amal; Chiesa, Matteo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)
      Chemical vapor transport synthesis of SnTiS3 yields a self-assembled heterostructure of two distinct constituent materials, the semiconductor SnS and the semimetal TiS2. The misfit layer compound, although thermodynamically stable, is structurally complex, and precise understanding of the structure is necessary for designing nanoengineered heterojunction compound devices or for theoretical studies. ...

    • A review of focused ion beam applications in optical fibers 

      Sloyan, Karen; Melkonyan, Henrik; Apostoleris, Harry; Dahlem, Marcus S.; Chiesa, Matteo; Al Ghaferi, Amal (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-02)
      Focused ion beam (FIB) technology has become a promising technique in micro- and nano-prototyping due to several advantages over its counterparts such as direct (maskless) processing, sub-10 nm feature size, and high reproducibility. Moreover, FIB machining can be effectively implemented on both conventional planar substrates and unconventional curved surfaces such as optical fibers, which are popular ...

    • What is going on with Middle Eastern solar prices, and what does it mean for the rest of us? 

      Apostoleris, Harry; Al Ghaferi, Amal; Chiesa, Matteo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-04)
      For the third time in a decade, solar energy pricing records are tumbling in the Persian Gulf. As each previous wave of new records was met with incredulity, only for these prices to become the new normal around the world within a few years, it would be unwise to once again dismiss low prices as unrepresentative outliers. In this study, we show how local conditions and global macroeconomic factors ...
