Etching selectivity and passivity of Al2O3 layers

The project focuses on etching properties of the atomic layer deposition (ALD) of Al2O3. For this purpose, etching processes such as plasma etch with sulfur hexafluoride (SF6), gas etch with xenon difluoride (XeF2), wet etch with MIF developer (726 MIF) as ...

Low-energy stereodynamics of ion-forming reactions

Junwen Zou

In this thesis, an experimental study of low-temperature stereodynamics in the reactive scattering of Ne(3P2) + X collisions (X = Ar, Kr, Xe, CO and N2) is presented. The steric effect of Ne(3P2) in these reactions is observed experimentally using a contro ...

What Are the Best Materials To Separate a Xenon/Krypton Mixture?

Berend Smit, Cory Matthew Simon, Rocio Mercado, Sondre Kvalvag Schnell

Accelerating progress in the discovery and deployment of advanced nanoporous materials relies on chemical insight and structure-property relationships for rational design. Because of the complexity of this problem, trial-and-error is heavily involved in th ...

Photosensitizing and Inhibitory Effects of Ozonated Dissolved Organic Matter on Triplet-Induced Contaminant Transformation

Urs von Gunten, Silvio Canonica

Dissolved organic matter (DOM) is both a promoter and an inhibitor of triplet-induced organic contaminant oxidation. This dual role was systematically investigated through photochemical experiments with three types of DOM of terrestrial and aquatic origins ...

Intricacies of Describing Weak Interactions involving Halogen Atoms within Density Functional Theory

Ursula Röthlisberger, Ivano Tavernelli

In this work we assess the performance of different dispersion-corrected DFT approaches (M06, M06-2X, DFT-D3 and DCACP) in reproducing high-level wave function based benchmark calculations on the weakly bound halogen dimers (X2)2 and X2-Ar (for X=F,Cl,Br,I ...

Spectroscopy on Rydberg states of sodium atoms on the surface of helium nanodroplets

Marcel Drabbels, Evgeniy Loginov

One- and two-photon excitation spectra of sodium atoms on the surface of helium droplets are reported. The spectra are recorded by monitoring the photoionization yield of desorbed atoms as function of excitation frequency. The excitation spectra involving ...

ArF laser induced refractive index and luminescence changes in Bi-doped aluminosilicate fibers - INVITED

Hans Georg Limberger, Christian Ban

Fibers doped with bismuth show broad luminescence bands around 750, 1100, and 1400 nm with spectral bandwidths of 100 to 200 nm at room temperature. The luminescence bands can be observed by pumping broad absorption bands in the visible or near infrared sp ...

Helium implanted gallium nitride evidence of gas-filled rod-shaped cavity formation along the c-axis

Guillaume Lucas

structural defects induced by He implantation in GaN epilayer at high fluence (1 X 10(17) He/cm(2)) and elevated temperature (750 degrees C) have been studied by conventional and high resolution transmission electron microscopy. In addition to the planar i ...

Preparation of stable AsBr4+ and I2As-PI3+ salts. Why didn't we succeed to prepare AsI4+ and As2X5+? A combined experimental and theoretical study

In analogy to the authors' successful PX2+ insertion reactions, an AsX2+ insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepd.: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from ...

A thallium coated dianion: trigonal bipyramidal [F2Al(OR)3]2- coordinated to three Tl+ cations in the ion pair [Tl3F2Al(OR)3]+[Al(OR)4]- [R = CH(CF3)2]

The reproducible synthesis of the unusual ionic aluminum compd. [Tl3F2Al(OR)3]+[Al(OR)4]- (1) is reported. In the reaction of Li[Al(OR)4] [R = C(H)(CF3)2] with TlF the initially desired Tl[Al(OR)4] only formed with an exact 1:1 stoichiometry, while an exce ...
