Opis:: The photoelectromagnetic investigations of graphene has been performed using noncontact technique. The dependence of photoelectromagnetic response on magnetic field induction, illumination intensity for different photon energies, and frequency of illumination chopping is presented. We anticipate our paper to be a starting point for investigations of carrier diffusion length in this material. Such investigations should be essential for development of graphene electronic and optoelectronic devices.

Opis:: This paper presents for the first time temperature dependences of optical energy gaps of SbSI@CNT and SbSeI@CNT, i.e. carbon nanotubes (CNTs) filled with antimony sulfoiodide (SbSI) and antimony selenoiodide (SbSeI). The heterostructures were prepared sonochemically using CNTs and elemental Sb, S or Se and I in the presence of solvent under ultrasonic irradiation. Spectral characteristics of diffusive transmittance and reflectance of SbSI@CNT and SbSeI@CNT were measured in temperature range 274 K < T < 333 K. The determinal temperature dependence of indirect forbidden optical energy gap of SbSI@CNT has been fitted with $E_\text{gIf} (T) = (1.92(2)-3.6(6) \times 10^{-4} \times T) eV$. Indirect allowed optical energy gap of SbSeI@CNT has been fitted with $E_\text{gIa} (T) = (1.817(5)-7.1(2) \times 10^{-4} × T) eV$.

Opis:: For the first time influence of humidity on photoconductivity transient characteristics are studied for antimony sulfoiodide (SbSI) single nanowires. While negative photoconductivity is observed for SbSI gel, made up of large quantity of nanowires, only the positive effect occurs for SbSI single nanowires. Photoconductivity current response on switching on and off illumination in moist $N_{2}$ represents so-called hook anomaly.

Opis:: For the first time the thermal desorption of $H_2$, $N_2$, $O_2$ and $CO_2$ is presented for antimony sulfoiodide (SbSI) xerogel made up of large quantity nanowires. The desorption has been observed near ferroelectric phase transition established at $T_{c}$=293.0(2) K. The Sievert measurements have shown that the hydrogen uptake is linear function of $H_2$ pressure (when p < 1.1×$10^5$ Pa). The hydrogen storage density in SbSI gel amounted 1.24× $10^{-2}$ wt% (for p = 1.08×$10^5$ Pa at room temperature).

Opis:: For the first time current quantization is reported for antimony sulfoiodide (SbSI) nanowires. It has been registered in current responses on electric field switching as well as on illumination on and off. Current steps determined in all experiments have been equal to each other within the experimental error. It has been explained by the quantized change of free carrier concentration in nanowire. Lateral dimensions of SbSI nanowires estimated from quantum steps are comparable with geometrical data reported for the same technology of material preparation.

Opis:: Nanoparticles of chalcopyrites copper indium gallium sulfide ($CuIn_{x}Ga_{1-x}S_{2}$ or CIGS) and copper indium gallium selenide ($CuIn_{x}Ga_{1-x}Se_{2}$ or CIGSe) were fabricated sonochemically. They were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, high resolution transmission electron microscopy, selected area electron diffraction, and diffuse reflectance spectroscopy. The electrical and photoelectrical properties of the fabricated nanomaterials were investigated.
