Oxygen Distribution of Fluorine-doped Tin Oxide Films Coated on Float Glass along Depth Before and After Heat Treatment

Fluorine-doped tin oxide (FTO) films were deposited on float glass to create low-emissivity glass (low-E glass) by atmospheric pressure chemical vapor deposition (APCVD). Heat treatments were carried out to assess its antioxidant properties. The surface mo ...

Pressure dependence of the large-polaron transport in anatase TiO2 single crystals

Helmuth Berger, László Forró, Richard Gaal, Arnaud Magrez, Jacim Jacimovic, George Cristian Vaju, Radomir Zikic

We have measured the pressure and temperature dependences of the resistivity and the thermoelectric power of anatase, TiO2. The resistivity varies with T-3 at high temperatures, and its absolute value is in the 1 Omega cm range. Below 60 K, the resistivity ...

From All-Si Nanowire TFETs Towards III-V TFETs

Hesham Ghoneim

Performance improvement by device scaling has been the prevailing method in the semiconductor industry over the past four decades. However, current silicon transistor technology is approaching a fundamental limit where scaling does not improve device perfo ...

Nature of the Charge Carriers and Conduction Mechanism in Anatase TiO2

Jacim Jacimovic

The anatase phase of TiO2 is a key material in the third generation of photovoltaics and for photo-catalytic devices. The number of promising applications, where one would profit from the electronic degrees of freedom of the material, like in memristors, s ...

Polarization Screening in Multiferroic (Ga,Mn)As/P(VDF-TrFE) Transistors

Nava Setter, Igor Stolichnov, Evgeny Mikheev, Sebastian Riester

Ferroelectric copolymers of polyvinylidene fluoride and trifluoroethylene are attractive gate materials because of a rather high remanent polarization, low dielectric permittivity, and easy integration on semiconductors due to the low processing temperatur ...

Gallium assisted plasma enhanced chemical vapor deposition of silicon nanowires

Anna Fontcuberta i Morral, Libo Yu, Sonia Conesa Boj, Père Roca i Cabarrocas

Silicon nanowires have been grown with gallium as catalyst by plasma enhanced chemical vapor deposition. The morphology and crystalline structure has been studied by electron microscopy and Raman spectroscopy as a function of growth temperature and catalys ...
