Bi2Sr2Ca1Cu2OX film prepared using 266 nm YAG laser

Stoichiometric transfer of material in the infrared pulsed laser deposition of yttrium doped Bi-2212 films

“…The literatures abound with reports of pulsed laser deposition (PLD) of Bi-Sr-Ca-Cu-O (BSCCO) films using UV excimer or Nd:YAG lasers [11][12][13][14][15][16][17][18]. This technique allows for the deposition of smooth nanometer-scale thin films with electrical properties suitable for many applications [11][12][13][14][15][16].…”

“…This technique allows for the deposition of smooth nanometer-scale thin films with electrical properties suitable for many applications [11][12][13][14][15][16]. However, the high UV photon energy of the excitation laser induce photochemical reaction both in the ablated area and the plasma plume that leads to cationic variation in the deposited films [10,18,19].…”

“…In this technique, the substrates are usually heated at relatively high temperatures in oxygen gas atmosphere [20]. These conditions can lead to cationic composition variation and most importantly, oxygen composition variation in the deposited films [14,15]. In some studies with KrF (k = 248 nm) excimer laser deposition of Bi-2212, the deposited films showed Ca, Cu and Sr content variation [14,16,17].…”

“…The films composition is usually different from the PLD target composition [14][15][16][17][18]. It is normally necessary to use finely tuned set of deposition parameters such as laser fluence, repetition rate, target-to-substrate distance, substrate temperature, background gas atmospheres and target composition for UV PLD.…”

Electrochemical Response of Platinum Ultrathin Layer Formed by Pulsed Laser Deposition

“…ULPt was prepared by using a Q switched Nd:YAG laser (SL803G, Spectron Laser Systems Ltd., England) with its fourth harmonics (266 nm) operating at 2 Hz [19,20]. The laser influence was adjusted at 2 J/cm 2 .…”
