Transport properties of flash-evaporated (Bi1 − xSbx)2Te3 films I: Optimization of film properties

Thermal sensors based on Sb2Te3 and (Sb2Te3)70(Bi2Te3)30 thin films

“…In recent years, considerable attention has also been devoted to Sb 2 Te 3, Bi 2 Te 3 and their alloys because of their potential applications in the fabrication of thermoelectric devices based on the Seebeck effect, such as thermal sensors, hyper frequency power sensors, thermopiles, and wide-band radiation detectors Therefore, with increasing interest in thin film thermoelectric devises, attempts have been made to deposit and investigate the (Sb 2 Te 3 -Bi 2 Te 3 ) alloys. Using several techniques [5][6][7][8][9], Sb 2 Te 3 films were grown on various substrates such as SiO 2 [5], mica [10] or polymide [11][12][13][14][15]. p-type samples have been reported to contain a telluriumrich second phase whose effect on the thermoelectric properties is deleterious as reported by Airapetiants [16], Tiller [17], and also by W.Yim et al [18].…”

Fabrication and characterization of Bi0.4Te3.0Sb1.6 thin films by flash evaporation method

“…There are presently many deposition methods such as flash evaporation [6][7][8], co-sputtering [9,10], pulsed laser deposition [11,12], metal organic chemical vapor deposition (MOCVD) [13,14] and molecular beam epitaxy (MBE) [15][16][17]. Thus, although there are many deposition methods, the resulting devices are not yet appropriate for commercial viability because of higher production costs due to expensive equipments, and/or inadequate thin film properties.…”

Effect of pH on Structural and Electrical Properties of Electrodeposited Bi2Te3 Thin Films

“…These materials find their application in electronic devices such as sensors 4 and coolers. 5 Bi 2 Te 3 thin films have been deposited by various techniques such as flash evaporation, 6 sputtering, 7 electrochemical deposition, 8,9 through interfacial reaction, 10 electrochemical atomic-layer epitaxy, 11 metalorganic chemical vapor deposition, 12 and vacuum deposition. 13 Among these various methods, electrochemical deposition is relatively simple and cost effective with several advantages.…”
