“…For comparison, the average measured isothermal bulk modulus of Sc 2 O 3 reported herein is 188 ± 10 GPa . The brief overview of the mechanical and elastic properties of Sc 2 O 3 was done previously . The obtained in the present research hardness of Sc 2 O 3 films are higher when compared with pure hafnium oxide films (monoclinic phase, H = 18 GPa), and comparable with hafnium oxide of high‐temperature phases stabilized by nitrogen (tetragonal/cubic, H = 20 GPa) .…”

“…The fracture toughness, K IC , of the hot-pressed LLTO samples was determined using the indentation technique [17][18][19][20][21][22][23][24][25][26]. A typical pyramid-shaped Vickers indenter was employed with a load of 0.3 kg for 15 s to induce cracks that extended from the indent corners, from which the crack sizes were determined optically.…”

“…The H/G values for LLTO, LLZO, and LATP were similar, suggesting that they all have the same type of dominant bonding: Covalent bonding. Table 2 lists the fracture toughness values of LLTO-SG and LLTO-SS using different equations to determine K IC from the indentation crack lengths [17][18][19][20][21][22][23][24][25][26]. The long straight cracks are indicative of a brittle material [25][26][27].…”

“…Although Vb had little affected the coating crystalline structure, it did affect the coating hardness. The bulk hardness of Er2O3 is about 7 GPa [18], which is about the hardness of coatings deposited with Vb= -20V. However, when Vb was -40 V, HK varied with P, with the highest hardness, HK= 10 GPa at the lowest pressure, P= 0.40 Pa and the lowest hardness of HK= 4 GPa at the highest pressure, P= 0.93 Pa.…”
