“…According to the reported results, the primary slip system for sphalerite ZnSe is (111)<110> [46,47]. Thus, in our calculations, we constructed a model of ZnSe crystal with three dimensions along [1][2][3][4][5][6][7][8][9][10], and [111] directions. The front view and top view of the atomic arrangement can be found in Figure 2a,b.…”

“…In addition, the energy barrier along In our calculations, the constructed ZnSe models are divided into two parts by the (111) crystalline plane, as illustrated as the dash line in Figure 2a. By rigidly displacing two halves of the ZnSe crystal on the (111) crystalline plane along [1][2][3][4][5][6][7][8][9][10] and directions, the stacking fault can be generated. Through optimizing the obtained structure by the CG algorithm, the potential energy of the ZnSe system can be calculated.…”

“…Because of these excellent properties, ZnSe materials are widely used in nonlinear optical devices, flat panel displays, light emitting diodes (LEDs), lasers, logic gates, transistors, etc. [8][9][10][11][12][13][14]. In addition to thin films and macroscopic crystals, ZnSe has been obtained in a great variety of morphologies in the nanometric range, that make it suitable for applications such as field emitters, sensors, actuators, and many other optoelectronic devices [9,11,15,16].…”

Although ZnSe has been widely studied due to its attractive electronic and optoelectronic properties, limited data on its plastic deformations are available. Through molecular dynamics simulations, we have investigated the indentations on the (001), (110), and (111) planes of ZnSe nano films. Our results indicate that the elastic modulus, incipient plasticity, elastic recovery ratio, and the structural evolutions during the indenting process of ZnSe nano films show obvious anisotropy. To analyze the correlation of structural evolution and mechanical responses, the atomic displacement vectors, atomic arrangements, and the dislocations of the indented samples are analyzed. Our simulations revealed that the plastic deformations of the indented ZnSe nano films are dominated by the nucleation and propagation of 1/2<110> type dislocations, and the symmetrically distributed prismatic loops emitted during the indenting process are closely related with the mechanical properties. By studying the evolutions of microstructures, the formation process of the dislocations, as well as the formation mechanisms of the emitted prismatic loops under the indented crystalline planes are discussed. The results presented in this work not only provide an answer for the questions about indentation responses of ZnSe nano films, but also offer insight into its plastic deformation mechanisms.

“…It cannot be ruptured under normal mechanical pressure or impact. Due to its excellent chemical and physical properties, ZnSe has been widely used in solar cells, lasers, logic gates, flat panel displays and transistors [ 12 , 13 , 14 , 15 ]. Recently, ZnSe has garnered tremendous interest because of its valuable potential for both basic physical research and applications in micro-nano component construction.…”

Rapid Fabrication of Large-Area Concave Microlens Array on ZnSe

et al. 2021

View full text Add to dashboard Cite

A rapid and single-step method for the fabrication of a zinc selenide (ZnSe) concave microlens array through the high-speed line-scanning of a femtosecond laser pulse is presented. Approximately 1.1 million microlenses, with minimized volume and high transparency at wavelengths between approximately 0.76–20 μm were fabricated within 36 min. More importantly, the size of the microlenses can be controlled by adjusting the laser power. Their high-quality infrared optical performance was also demonstrated. This method holds great promise for the development of ZnSe-based micro-optical devices.

“…The absence of extra peaks confirms non-appearance of secondary impure phase. As shown in figure 1, addition of copper ions into ZnAl 2 O 4 nano aluminates indicated by peak shift from higher diffracting angle to lower diffracting angle.The lattice parameters are estimated[29] and shown in table 1 for Zn 1−x Cu x Al 2 O 4 (0x0.5) nano aluminates. The value of lattice parameters decreases from 8.140 Å to 8.100 Å as increases Cu 2+ ion concentrations in zinc aluminates.…”

Zn 1−x Cu x Al 2 O 4 nanoparticles were prepared by microwave combustion technique with metal nitrates as precursor materials. Powder x-ray diffraction studies confirm the formation of single phase of spinel pure and copper doped zinc aluminates. HR-SEM images reveal the agglomerated coalescence morphology with pores. Elemental analysis (EDX) confirm the presence of Zn, Cu, Fe and O. UV-Visible Diffuse reflectance spectroscopy is used to find the optical bandgap and it is found to decreases from 5.45 eV to 3.57 eV. IR spectra show three major peaks which confirm the phase formation of Zn 1−x Cu x Al 2 O 4 nano aluminates with spinel structure. Vibrating sample magnetometer (VSM) measurements reveal the super paramagnetic nature of pure and copper doped zinc alumintes. The obtain results are confirmed that present pure and copper doped ZnAl 2 O 4 particles at nanoscale are to be potential candidate for catalytic, sensor and optoelectronic device applications.
