Silicate glass-to-glass hermetic bonding for encapsulation of next-generation optoelectronics: A review

Lateral‐pushing induced surface lift‐up during nanoindentation of silicate glass

“…The Nano Indenter G200 (KLA Corporation, USA) system is applied to perform the nano-indentation tests. Four commercial silicate glass samples, that is, a fused silica (SiO 2 , Kejing, China), 38 a borosilicate glass (Borofloat R 33 (Boro33), SCHOTT, Germany), 25 a lithium aluminosilicate glass (non-ion-exchanged Xensation R Up (UP, SCHOTT, Germany)), 39 and a soda-lime silicate glass (SLS, AGC, Japan) 38 were used in the nano-indentation tests. The atomic packing density (C g ) is defined as the ratio of the actual volume occupied by the constituent elements to the corresponding effective volume of glass 12 following Shannon's ionic radii.…”

A Thorough Investigation of Electronic, Optical, Mechanical, and Thermodynamic Properties of Stable Glasslike Sodium Germanate under Compressive Hydrostatic Pressure: Ab Initio Study

“…Wide band gap semiconductor materials have received extensive research attention due to their high-temperature structural stability and tunability in electronic and mechanical characteristics. − Among the wide band gap semiconductors, glasslike materials possessing a band gap ( E g ≥ 2.5 eV) have become a fascinating material both experimentally and theoretically due to their unique properties such as high mechanical and thermodynamical stabilities, low thermal conductivity, abundant availability in nature, and so on. − Flexibility in fabrication and reliability of the glass materials have made them promising candidates for technological and industrial uses, particularly in the field of battery and storage systems, fireproof fabrics, fiber optics, electronic device preparation, bioactive glass, substrates for solar cells, etc. − It is well-known that the majority of the glasses are silica (SiO 2 ) based material. − Despite the fact that silicate glasses are the most commonly utilized among different glass types, they have some major drawbacks including their brittleness and impact resistance, property losses at higher temperatures, etc. Therefore, in order to avoid such problems and to use them for a wide range of temperatures, a replacement of silicate glass is necessary.…”

Electronic, mechanical and piezoelectric properties of glass-like complex Na2Si1−xGexO3 (x = 0.0, 0.25, 0.50, 0.75, 1.0)

“…[14][15][16] As reported, silicate glasses have high technological importance in industry and in commercial applications: battery and storage systems, opto-electronic devices, and auxetic materials having high performances in the elds of bio-medicine, surgical implants and piezoelectric sensors and actuators, reproof fabrics, optical bres, lighting technology, and many more. [17][18][19][20][21] The pioneering work of Randall et al 22 suggested that silicate glass structures were thought to be well understood at a local level and reported that vitreous silica probably consists of small crystals of cristobalite that were formed at very high temperatures by performing an experimental investigation using X-ray diffraction (XRD). Zachariasen et al 23 have investigated heattreated specimens by using XRD and reported a complex silicate glass structure.…”
