Abstract Single crystals of Piperazine Zirconium Oxy-Chloride (PzZrOCl) are grown successfully by slow evaporation technique for Opto-electronic device applications. Suitability of the material is estimated and reported as follows. Crystal habits, purity, crystallite size, microstructure and bulk crystals structures are essential parameters for device compatibility hence they were examined with basic characterization techniques and studied to estimate their effects on optoelectronic properties. The outcomes from structural aspects are reasonably good. The functional groups of a molecule, their bond vibration frequencies and mode of alignments have been examined by Fourier Transform Infrared spectroscopy (FT-IR). The transmittance (98%) in the entire visible range with lowest cut-off wavelength (215 nm) and green emission (545 nm) is another evidence of suitability. The thermal and mechanical strength via hardness, Mayer index, yield strength and elastic stiffness constant is evaluated; it is thermally stable up to 162°C, mechanically strong and belongs to soft category. Laser induced damage is estimated by using Nd:YAG laser of wavelength 1064 nm and the observed values is three times higher than KDP, 1.2 times higher than LAPP. The optical nonlinear nature and its efficiency are examined by using Z-scan technique. The analysis discussed in detailed and the results strongly recommends PzZrOCl single crystals are suitable for optical and electronic device applications.

Abstract The past several decades have witnessed a vast array of developments in printable organic semiconductors, where successes both in synthetic chemistry and in printing technology constituted a key step forward to realization of printed electronics. In this review, we highlight specifically on materials science, charge transport, and device engineering of —two-dimensional single crystals—. Defect-free organic single-crystalline wafers manufactured via a one-shot printing process allows remarkably reliable implementations of organic thin-film transistors with decently high carrier mobility up to 10 cm2 V-1 s-1, which has revolutionized the current printing electronics to be able to meet looming IoT challenges. This review focuses on the perspective of printing two-dimensional single crystals with reasonable areal coverage, showing their promising applications for practical devices and future human society, particularly based on our recent contributions.

AbstractWe have measured the resistivity and thermopower of single crystals as well as polycrystalline pressed powders of the low-dimensional pentatelluride materials: HfTe5 and ZrTe5. We have performed these measurements as a function of temperature between 5K and 320K. In the single crystals there is a peak in the resistivity for both materials at a peak temperature, Tp where Tp ≈ 80K for HfTe5 and Tp ≈ 145K for ZrTe5. Both materials exhibit a large p-type thermopower around room temperature which undergoes a change to n-type below the peak. This data is similar to behavior observed previously in these materials. We have also synthesized pressed powders of polycrystalline pentatelluride materials, HfTe5 and ZrTe5. We have measured the resistivity and thermopower of these polycrystalline materials as a function of temperature between 5K and 320K. For the polycrystalline material, the room temperature thermopower for each of these materials is relatively high, +95 μV/K and +65 μV/K for HfTe5 and ZrTe5 respectively. These values compare closely to thermopower values for single crystals of these materials. At 77 K, the thermopower is +55 μV/K for HfTe5 and +35 μV/K for ZrTe5. In fact, the thermopower for the polycrystals decreases monotonically with temperature to T ≈ 5K, thus exhibiting p-type behavior over the entire range of temperature. As expected, the resistivity for the polycrystals is higher than the single crystal material, with values of 430 mΩ-cm and 24 mΩ-cm for Hfre5 and ZrTe5 respectively, compared to single crystal values of 0.35 mΩ-cm (HfTe5) and 1.0 mΩ-cm (ZrTe5). We have found that the peak in the resistivity evident in both single crystal materials is absent in these polycrystalline materials. We will discuss these materials in relation to their potential as candidates for thermoelectric applications.
