  • Fabrication of quantum point contacts by engraving GaAs/AlGaAs heterostructures with a diamond tip 
    Regul, J.; Keyser, U.F.; Paesler, M.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Malavé, A.; Oesterschulze, E.; Reuter, D.; Wieck, A.D. (College Park, MD : American Institute of Physics, 2002)
    We use the all-diamond tip of an atomic force microscope for the direct engraving of high-quality quantum point contacts in GaAs/AlGaAs heterostructures. The processing time is shortened by two orders of magnitude compared ...
  • Ferroelectric nanocomposites with governed interface on base of magnetic porous glasses 
    Naberezhnov, A.A.; Alekseeva, O.A.; Golosovsky, I.V.; Sysoeva, A.A.; Vanina, P.Y.; Nacke, B.; Nikanorov, A. (Rēzekne : Rezekne Higher Education Institution, 2019)
    Two-phase (nonporous) magnetic alkali borosilicate glasses have been produced by induction melting. Their macroscopic properties and crystal structure have been studied and it is shown that in the silica skeleton there are ...
  • Integrated multimode optical waveguides in glass using laser induced deep etching 
    Reitz, Birger; Evertz, Andreas; Basten, Robin; Wurz, Marc Christopher; Overmeyer, Ludger (Washington, DC : Optical Soc. of America, 2024)
    Glass is an ideal material for optical applications, even though only a few micromachining technologies for material ablation are available. These microstructuring methods are limited regarding precision and freedom of ...
  • Introducing pinhole magnification by selective etching: Application to poly-Si on ultra-thin silicon oxide films 
    Tetzlaff, Dominic; Dzinnik, Marvin; Krügener, Jan; Larionova, Yevgeniya; Reiter, Sina; Turcu, Mircea; Peibst, Robby; Höhne, Uwe; Kähler, Jan-Dirk; Wietler, Tobias F. (Amsterdam : Elsevier, 2017)
    Carrier selective junctions formed by polycrystalline silicon (poly-Si) on ultra-thin silicon oxide films are currently in the spotlight of silicon photovoltaics. We develop a simple method using selective etching and ...
  • Local droplet etching on InAlAs/InP surfaces with InAl droplets 
    Cao, Xin; Zhang, Yiteng; Ma, Chenxi; Wang, Yinan; Brechtken, Benedikt; Haug, Rolf J.; Rugeramigabo, Eddy P.; Zopf, Michael; Ding, Fei (New York, NY : American Inst. of Physics, 2022)
    GaAs quantum dots (QDs) grown by local droplet etching (LDE) have been studied extensively in recent years. The LDE method allows for high crystallinity, as well as precise control of the density, morphology, and size of ...
