Alternating and direct current characterization and photoinduced absorption studies of modified conjugated polymer thin films
(2004)
Control of interchain separation enables the optical properties of polymer thin films to be altered. We present a thin film preparation technique that increases the free volume fraction in spin coated polymer thin films ...
Determination of bulk domain structure and magnetization processes in bcc ferromagnetic alloys: Analysis of magnetostriction in Fe83Ga17
(2018)
The ground state of macroscopic samples of magnetically ordered materials is a domain state because of magnetostatic energy or entropy, yet we have limited experimental means for imaging the bulk domain structure and the ...
Empirical Modelling of Public Lighting Emission Functions
(2021)
Study of light at night has increased in recent decades due to the recognition of its impact on the environment, potential health concerns, as well as both the financial and carbon cost of energy waste. The advent of more ...
High-resolution near-field measurements of microwave circuits
(2004)
In this paper we report on measurements of electric field intensities of microwave field above surface of microwave
circuits using miniaturized coaxial antennas. During the scanning process the antenna is driven at ...
Transport and optical gaps and energy band alignment at organic-inorganic interfaces
(2013)
The transport and optical band gaps for the organic semiconductor tin (II) phthalocyanine (SnPc) and the complete energy band profiles have been determined for organic-inorganic interfaces between SnPc and III-V semiconductors. ...
Can soap films be used as models for mortality studies?
(2018)
We report studies of the life expectancy of sets of parallel liquid films made from surfactant solution and contained in cylindrical perspex tubes. The tubes are sealed at the bottom and vertically placed. From our analysis ...
Magnetic interaction of Co ions near the {10\bar{1}0} ZnO surface
(2010)
Co-doped ZnO is the prototypical dilute magnetic oxide showing many of the characteristics of ferromagnetism. The microscopic origin of the long range order however remains elusive, since the conventional mechanisms for ...
Quantum conductance of a single magnetic atom: An ab initio study
(2010)
Our
ab initio
study explains recent puzzling experiments on the conductance of a single Co adatom depos-
ited either on Cu
111
or on ferromagnetic Co islands and contacted with both magnetic and nonmagnetic
electrodes
N. ...
Study of polarization-dependent energy coupling between near-field optical probe and mesoscopic metal structure
(2004)
We present an experimental study of the coupling of light from a probe of a scanning near-field optical microscope (SNOM) into a mesoscopic structure consisting of gold stripes with varying separations. We demonstrate that ...
Stability and capping of magnetite ultra-thin films
(2014)
Ultrathin films of Fe3O4 have been grown epitaxially on nearly lattice matched MgO(001). The stability of
4 nm thick films in ambient air and under annealing in an oxygen atmosphere at 200◦C has been studied. By
magneto ...
