    Abstract : Due to the constantly decreasing dimensions of electronic devices, the conventional dielectric material in transistors and capacitors, SiO2, has to be replaced by a material with higher dielectric constant. Some of the most promising candidates are tantalum oxide,Ta2O5, zirconium oxide, ZrO2 and hafnium oxide, HfO2. READ MORE

  4. 4. Alkoxide complexes of rhenium, niobium and tantalum

    University dissertation from ; Department of Chemistry, Swedish University of Agricultural Sciences

    Author : Olesya Nikonova; Sveriges lantbruksuniversitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes two major methods for preparation of new mono-, bi- and trimetallic complexes on the basis of Rhenium, Niobium and Tantalum: (1) - the electrochemical method for the synthesis of Re4O4(OEt)12 and (2) - the interaction of Rhenium heptoxide, Re2O7, with alkoxo-derivates of Niobium and/or Tantalum, M2(OR)10 for the synthesis of bi- and trimetallic complexes of common formula (M1-xM'x)4O2(OR)14(ReO4)2 (M = Nb; M' = Ta; R = Me, Et), where x = 0–1. The structures of these complexes were determined by single-crystal X-ray diffraction. READ MORE

  5. 5. Tunnel Emitter Transistors

    University dissertation from ; Department of Chemistry, Swedish University of Agricultural Sciences

    Author : Erik Aderstedt; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TET; tunneling; siO2< sub>; tunnel emitter transistor; MOS; Ta2< sub>O5< sub>; silicon; high- #954; BICFET; dielectrics;

    Abstract : The Tunnel Emitter Transistor is based on the modulation of the tunnel current in a Metal Oxide Semiconductor (MOS) structure with an ultra-thin oxide layer. The modulation is accomplished by injecting charge to the oxide-semiconductor interface from a third terminal. READ MORE
