Generation of phase-change Ge–Sb–Te nanoparticles by pulsed laser ablation

Microstructure and optical properties of phase-change Ge–Sb–Te nanoparticles grown by pulsed-laser ablation

“…A focused laser beam is aligned onto the target, which is rotating during ablation in order to prohibit the target from making caters. Details on growth conditions have been reported elsewhere [14].…”

Growth and structural properties of pulsed laser-ablated CuInSe2 nanoparticles by pulsed-laser ablation and selenization process

“…In many cases of CIS-based nanoparticles, they indicate similar results with thin-films [12,21]. However, since it is anticipated that micro-structural change in nanoparticles owing to their decreased size, it is worthy to study detailed analysis of CIS nanoparticles.…”

“…This study also examined CIS nanoparticles but synthesized by pulsed laser ablation (PLA) and characterized their behavior. PLA has been widely used to make thin-films with multi-elements and demonstrates a powerful tool for growing highly pure and composition-controlled nanoparticles [12][13][14][15]. Production rate of nanoparticles by PLA is known as very high [12] and the amounts of nanoparticles are strongly dependent on laser power of the laser.…”

“…The production method of GST nanoparticles by in-situ pulsed laser ablation was described in our previous work. 11 We used a KrF excimer pulsed laser with the wavelength of 248 nm and laser pulse rate and pulsewidth were 5 Hz and 30 ns, respectively. As-grown nanoparticles mostly have a stoichiometric composition of Ge 2 Sb 2 Te 5 phase when the temperature of heat treatment is close to 250 C with Ar flowing gas.…”
