Electric-field-induced phase transitions have been evidenced by macroscopic strain measurements at temperatures between 25 degrees C and 100 degrees C in 001-poled (1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) [(PMN-xPT);x=0.25,0.305,0.31] and (1-x)Pb(Zn1/3Nb2/3)O ...
Based on the results of field-dependent dielectric and magnetic measurements, we observe several interesting behaviors and phase transitions in this geometrically frustrated spinel system CdCr2S4. (1) A glassy dipolar state occurs near T-C similar to 85 K, ...
The internal electric field in multilayer organic light-emitting diodes (OLEDs) is investigated using a combination of experimental measurement and numerical device modeling. This approach results in a detailed understanding of the functioning of a multila ...
Thermally detected optical absorption (TDOA) and photoluminescence experiments were carried out on InGaN/GaN multi-quantum well (MQW) structures grown by molecular beam epitaxy on (0001) sapphire substrates. The absorption coefficient of the QW was extract ...
In this paper we present and discuss measurements of electric (vertical and radial) and magnetic fields from leaders and return strokes associated with lightning strikes to the 100 m tall Gaisberg tower in Austria obtained in 2007 and 2008. The fields were ...
Alginate gel formation on-chip is presented in the first part of this thesis. The technique allows immobilization, and release, of biological cells on-chip. Furthermore, via layer by layer deposition, a locally heterogeneous environment can be generated at ...
We present a novel method for accurately splitting ionic samples at microchannel bifurcations. We leverage isotachophoresis (ITP) to focus and transport sample through a one-inlet, two-outlet microchannel bifurcation. We actively control the proportion of ...
In this article, we present a semiclassical approach for modeling of electro-optic (EO) effect. We calculate phase retardation between x and y polarizations of optical electric field when a transverse external electric field is applied. Our results are wel ...
Highly sensitive photodetectors for the mid infrared have been obtained by placing a photodiode inside a Fabry Perot cavity. These resonant cavity enhanced detectors (RCED) are sensitive at the resonances only, which depend on the distance between the two ...
The origin of a recently reported peculiar phenomenon-polarization reversal against the applied electric field in ferroelectric thin films [M. Aplanalp and P. Gunter, Ferroelectrics 258, 3 (2001), T. Morita and Y. Cho, Appl. Phys. Lett. 84, 257 (2004)]-has ...
