Atomic-Layer-Deposited Transparent Electrodes for Silicon Heterojunction Solar Cells

We examine damage-free transparent-electrode deposition to fabricate high-efficiency amorphous silicon/crystalline silicon heterojunction solar cells. Such solar cells usually feature sputtered transparent electrodes, the deposition of which may damage the ...

Chemical Modification of Graphene via Hyperthermal Molecular Reaction

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Chemical functionalization of graphene is achieved by hyperthermal reaction with azopyridine molecular ions. The one-step, room temperature process takes place in high vacuum (10(7) mbar) using an electrospray ion beam deposition (ES-IBD) setup. For ion su ...

Advances in 3D focused ion beam tomography

Marco Cantoni

This article summarizes recent technological improvements of focused ion beam tomography. New in-lens (in-column) detectors have a higher sensitivity for low energy electrons. In combination with energy filtering, this leads to better results for phase seg ...

Silica-surface reorganization during organotin grafting evidenced by Sn-119 DNP SENS: a tandem reaction of gem-silanols and strained siloxane bridges

David Lyndon Emsley, Aaron James Rossini

Grafting reactive molecular complexes on dehydroxylated amorphous silica is a strategy to develop ``single-site'' heterogeneous catalysts. In general, only the reactivity of isolated silanols is invoked for silica dehydroxylated at 700 degrees C ([SiO2-700 ...

High vacuum chemical vapour deposition of oxides: A review of technique development and precursor selection

Patrik Willi Hoffmann, Ali Dabirian, Yury Kuzminykh, Michael Oliver Reinke

Thin films of oxide materials are widely used for various types of applications. The selection of an appropriate deposition method depends on the aimed material and application. We review here a high vacuum chemical vapour deposition (HV-CVD) method, which ...

Growth and Activation of an Amorphous Molybdenum Sulfide Hydrogen Evolving Catalyst

Xile Hu, Heron Vrubel

Amorphous molybdenum sulfide films, prepared by electrodeposition, are a class of highly active catalysts for hydrogen evolution. The growth mechanism of the films and the true active species were unclear. Herein, we report a study of the growth and activa ...

The Effect of Aluminum in Solution on the Dissolution of Amorphous Silica and its Relation to Cementitious Systems

Karen Scrivener, Theodor Alexandre Emmanuele Chappex

One of the most serious causes of degradation of concrete is the alkalisilica reaction. Amorphous silicates present in certain aggregates react with the alkaline pore solution of the concrete to form a gel, which absorbs water and swells, leading to the ex ...

Measuring the thermal balance of a snow avalanche

Michael Lehning, Betty Sovilla, Tobias Jonas, Walter Steinkogler

Avalanches can exhibit many different flow regimes from powder clouds to slush flows. Flow regimes are largely controlled by the properties of the snow released and entrained along the path. Recent investigations showed the temperature of the moving snow t ...

Texture mechanisms and microstructure of biaxial thin films grown by oblique angle deposition

Alireza Karimi, Akshath Raghu Shetty

In order to understand the texture formation mechanism in thin films grown under oblique angle deposition (OAD), TiAlN films were deposited at room temperature (RT) under various incident angles. We show that both in-plane and out-of-plane crystallographic ...
