“…Expt. 21 Theo. 24 Figure 2 shows the normalized values a/a 0 , c/c 0 , c/a and V/V 0 of SnO (where a 0 , c 0 and V 0 are the structural parameters at zero pressure) for different pressure.…”

“…[9][10][11][12] Due to the variety of applications mentioned above, many researchers have paid attentions which are reported in recent years. [13][14][15][16][17][18][19][20][21][22][23][24] Specially, SnO 2 , have been largely studied because of its n-type semiconducting nature with wide band gap (3.6 eV), while research work on SnO are seldom reported due to its decomposing tendency at high temperature. 25,26 But during the last few years researchers have paid their attention.…”

“…Some results of experimental and theoretical studies on SnO have been reported. High pressure study of electronic and structural properties of SnO up to 10 GPa has been studied by Christensen et al 20 Giefers et al 21 has investigated the structural properties of SnO at high pressure up to 51 GPa. The pressure-induced phase transition in SnO has been studied by Lie et al 22 L. A. Errico 23 has studied the structural and electronic properties of SnO and SnO 2 .…”

“…Recently, a superconducting state of SnO at a pressure, p > 6 GPa is reported 27 where a maximum T c was found 1.4 K at 9.3 GPa. Though a phase transition of α-SnO to γ-SnO under pressure is reported [28][29][30] but such type of transition is not observed by the recent experiments carried out by Wang et al 26 and Giefers et al 21 It was concluded about the phase transition that this might be induced by non-hydrostatic conditions. This motivates us to perform a complete study of SnO under hydrostatic pressure.…”

This article reports the first-principles study of SnO under high pressure within the generalized gradient approximation (GGA). We have calculated the structural, elastic, electronic and optical properties of SnO. The elastic properties such as the elastic constants Cij, bulk modulus, shear modulus, Young modulus, anisotropic factor, Pugh ratio, Poisson's ratio are calculated and analyzed. Mechanical stability of SnO at all pressure is confirmed using Born stability conditions in terms of Cij. It is also found that SnO exhibits very high anisotropy. The energy band structure and density of states are also calculated and analyzed. The results show the semiconducting and metallic properties at 0 (zero) and high pressure, respectively. Furthermore, the optical properties are also calculated. All the results are compared with those of the SnO where available but most of the results at high pressure are not compared due to unavailability of the results.

“…This oxide has found wide application in laser sensors, as an anode material for lithium ion batteries, and as a photocatalyst [6][7][8][9]. Among known SnO preparation techniques, hydrothermal and micro wave assisted hydrothermal processes allow one to produce structures with various orientations of crystal growth faces and various surface morphologies [10][11][12][13]. Hydrothermal processing offers a number of advantages: high growth rate of large crystals, high nucleation rate, relatively low synthesis temperature, structural uniformity of the resulting materials, etc.…”

SnO powder with a specific surface area of 2 m 2 /g has been prepared by microwave assisted hydrothermal processing of an ammoniacal Sn 6 O 4 (OH) 4 suspension. We have examined the effect of pressure rise rate in a reaction mixture on the surface morphology and photocatalytic activity of SnO. Raising the pres sure has been shown to reduce the SnO synthesis time, without influencing the surface morphology of SnO or its photocatalytic activity for methyl orange photodegradation.

The structures, phase transition, mechanical properties, dynamic stability, and electronic properties of SnO polymorphs (α, γ, herzenbergite, B1, and B2 phases) under pressure have been studied using the first‐principles calculations. The obtained structural parameters are in agreement with the available data. According to the enthalpy–pressure curves of SnO, the pressure‐induced phase transitions are verified to be from α to γ at 0.94 GPa and from B1 to B2 at 49.1 GPa, respectively. The calculated elastic constants indicate that B2 and γ are unstable under zero pressure. With increasing pressure, there is stability–instability transition for B1, whose transition pressure is 20.6 GPa, respectively. Moreover, a range of mechanical stability is from 5.5 to 10.8 for α phase and from 3.4 to 14.3 GPa for γ phase. The corresponding elastic modulus has been analyzed under pressures. With regard to elastic anisotropy, a variety of methods are taken to analyze it and the causes of various anisotropic characters are explained. Phonon dispersions show the same dynamic stability of SnO with the mechanical stability. In addition, the density of states and charge density all reflect that the interactions between Sn and O elements are enhanced with the increasing pressure.
