Matrix isolation infrared spectra of nitrosyl halide (XNO) complexes with HX and X2 (X = Cl, Br) are presented. The r elative frequency shifts of the HX mode are modest (ClNO · H-Cl, !':..:v/v = = 0.045; BrNO·H-Br, Av/v = ·-0.026), indicating weak hydrogen bonds 1-3 kcal/mo!. These shifts are accompanied by significant shifts to higher frequencies in the XN-0 stretching mode (CIN-O · HCl, Av/v ...

The localized surface-plasmon resonance of metal nanoparticles corresponds to a classical charge oscillation of the quasi-free conduction electrons. In the case of noble-metal nanoparticles, interband transitions from the d electrons influence the spectra strongly. In addition, the inhomogeneity of the nanoparticles at the atomistic level becomes important for small sizes. Using the time-evolut...

Charge transport in organic thin film transistors takes place in the first few molecular layers in contact with the gate dielectric. Here we demonstrate that the charge transport pathways in these devices are extremely sensitive to the orientational defects of the first monolayers, which arise from specific growth conditions. Although these defects partially heal during the growth, they cause d...

We evaluate two novel reciprocal self-sensing methods for tapping-mode atomic force microscopy (TM-AFM) utilizing charge measurement and charge actuation, respectively. A microcantilever, which can be batch fabricated through a standard microelectromechanical system (MEMS) process, is coated with a single piezoelectric layer and simultaneously used for actuation and deflection sensing. The setu...

Differences in charge state distributions of hairpin versus linear strands of oligonucleotides are analyzed using electrospray ionization mass spectrometry (ESI-MS) in the negative ion detection mode. It is observed that the linear structures show lower charge state distribution than the hairpin strands of the same composition. The concentration of ammonium acetate and the cone voltage are majo...

The negatively charged nitrogen vacancy (NV(-)) center in diamond has attracted strong interest for a wide range of sensing and quantum information processing applications. To this end, recent work has focused on controlling the NV charge state, whose stability strongly depends on its electrostatic environment. Here, we demonstrate that the charge state and fluorescence dynamics of single NV ce...

We study the self-force acting on static electric or scalar charges inside or outside a spherical, massive, thin shell. The regularization of the self-force is done using the recently proposed mode sum regularization prescription. In all cases the self-force acting on the charge is repulsive. We find that in the scalar case the force is quadratic in the mass of the shell, and is a second post-N...

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt età la diffusion de documents scientifiques de niveau r...

The optical excitation of organic semiconductors not only generates charge-neutral electron-hole pairs (excitons), but also charge-separated polaron pairs with high yield. The microscopic mechanisms underlying this charge separation have been debated for many years. Here we use ultrafast two-dimensional electronic spectroscopy to study the dynamics of polaron pair formation in a prototypical po...

The main objective of this paper is to replace autotransformers and transformers in industrial applications by switched capacitor three phase AC-AC converters. The control system is not required in case of open loop operation of AC-AC converters. In this paper, by employing closed loop system, the advantages such as accuracy, reduced error, reliability, fast response and less noise can be ensur...
