Abstract Solution‐processed tin oxide (SnO x ) electron transport layers demonstrate excellent performance in various optoelectronic devices and offer the ease of facile low cost deposition by printing techniques. The most common precursor solution for preparation SnO thin films is SnCl 2 dissolved ethanol. In order to elucidate mechanism conversion at different annealing temperatures layer, phonon vibrational infrared photoelectron spectroscopies as well atomic force microscopy are used...
Abstract Understanding the solid target dynamics resulting from interaction with an ultrashort laser pulse is a challenging fundamental multi-physics problem involving atomic and solid-state physics, plasma physics. Knowledge of initial interplay underlying processes essential to many applications ranging low-power regimes like laser-induced ablation high-power laser-driven ion acceleration. Accessing properties so-called pre-plasma formed as pulse’s rising edge ionizes complicated...
We demonstrate high-harmonic generation for the time-domain observation of electric field (HHG-TOE) and use it to measure waveform ultrashort mid-infrared (MIR) laser pulses interacting with ZnO thin-films or WS
Strong-field ionization can induce electron motion in both the continuum and valence shell of parent ion. Here we report on a joint theoretical experimental investigation laser-induced diffraction xenon. We explore interplay recollision with spin-orbit dynamics xenon cation. On theory side, electron-hole potentials for two different states are constructed, quantitative rescattering model is used to calculate photoelectron momentum distributions (PMDs) high-order above-threshold Measurements...
Strong-field ionization can induce electron motion in both the continuum and valence shell of parent ion. Here, we explore their interplay by studying laser-induced diffraction (LIED) patterns arising from interaction with potentials two-hole states xenon cation. The quantitative rescattering theory is used to calculate corresponding photoelectron momentum distributions, providing evidence that spin-orbit dynamics could be detected LIED. We identify contribution these time-evolving hole...
Above-treshold ionization (ATI) by femtosecond laser pulses centered at 515\,nm is studied for a gas mixture containing the Van-der-Waals complex Ar-H$_2$O. By detecting photoions and -electrons in coincidence, ATI spectra Ar, Ar$_2$, \HHO, Ar-\HHO are discerned measured simultaneously. Using an intensity-scanning technique, we observe red-shift of as function intensity. The intensity-dependent shift peak positions observed Ar-H$_2$O H$_2$O match but significantly differ from ones Ar Ar$_2$....

Above-threshold ionization (ATI) by femtosecond laser pulses centered at 515 nm is studied for a gas mixture containing the van der Waals complex $\mathrm{Ar}\text{\ensuremath{-}}{\mathrm{H}}_{2}\mathrm{O}$. By detecting photoions and photoelectrons in coincidence, ATI spectra Ar, ${\mathrm{Ar}}_{2},{\mathrm{H}}_{2}\mathrm{O}$, Ar-${\mathrm{H}}_{2}\mathrm{O}$ are discerned measured simultaneously. Using an intensity-scanning technique, we observe red shift of as function intensity. The...
Understanding the target dynamics during its interaction with a relativistic ultrashort laser pulse is challenging fundamental multi-physics problem involving at least atomic and solid-state physics, plasma physics. Already, properties of so-called pre-plasma formed as pulse's rising edge ionizes are complicated to access in experiments modeling, many aspects this laser-induced transition from solid overdense over picosecond time scales still open questions. At same time, applications like...
