    Fabrication and characterization of Si1−xGex nanocrystals in as-grown and annealed structures: a comparative study 
    Sultan, Muhammad Taha; Maraloiu, Adrian Valentin; Stavarache, Ionel; Gudmundsson, Jon Tomas; Manolescu, Andrei; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia; Svavarsson, Halldor (Beilstein Institut, 2019-09-17)
    Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...

    SiGe nanocrystals in SiO2 with high photosensitivity from visible to short-wave infrared 
    Stavarache, Ionel; Logofatu, Constantin; Sultan, Muhammad Taha; Manolescu, Andrei; Svavarsson, Halldor; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia (Springer Science and Business Media LLC, 2020-02-24)
    Films of SiGe nanocrystals (NCs) in oxide have the advantage of tuning the energy band gap by adjusting SiGe NCs composition and size. In this study, SiGe-SiO2 amorphous films were deposited by magnetron sputtering on Si substrate followed by rapid ...
