Studies on Magnetron Sputtered V2O5 Thin Films Deposited over ZnO Buffer Layer

“…V 2 O 5 at room temperature (RT) resembles yellow and it was also observed by earlier reported articles [30][31][32][33]. V 2 O 5 at room temperature (RT) resembles yellow and it was also observed by earlier reported articles [30][31][32][33].…”

Physicochemical properties of sprayed V2O5 thin films: Effect of substrate temperature

“…The orthorhombic unit cell structure of V 2 O 5 is the most stable form of the V-O system and consists of double zigzag chain of corner and edge sharing distorted VO 6 octahedra [9]. V 2 O 5 thin films have been prepared onto the different substrates by variety of physical and chemical deposition methods such as DC ion beam sputtering [10], sol-gel technique [11], spray pyrolysis [12], RF magnetron sputtering [13], chemical vapor deposition (CVD) [14], pulsed laser deposition (PLD) [15] and thermal evaporation [16].…”

Crystal structure development of vanadium oxide thin films deposited by a magnetron sputtering technique

“…Due to its unique layered structure V 2 O 5 shows interesting electronic and chemical properties and has applications in diverse areas such as chemical sensing, cathode material in batteries, electrochromic devices and catalysis. The obtained samples are amorphous [15][16][17][18][19] and can become crystalline if subjected to heat treatment, either by heating the substrate during the deposition or by a postdeposition heat treatment. Orthorhombic a-V 2 O 5 is the stable phase at ambient conditions.…”

“…1-4 V 2 O 5 exists in several polymorphs known as a, b, c, and d-V 2 O 5 . 15,20 The stable a-V 2 O 5 structure was recorded in a number of publications; [21][22][23][24][25][26] however, some reports mentioned growth of unstable b-V 2 O 5 phases. 5 c-V 2 O 5 is a metastable phase and can be obtained at atmospheric pressure by a reverse micelle technique 6 or deintercalation of Li from c-Li V 2 O 5 , 7 showing the back transition to a-V 2 O 5 at 340 C. b and d-V 2 O 5 are also metastable phases and can be modified from a-V 2 O 5 at high temperature and under high pressure by crystallographic shearing along c-axis.…”
