Laser deposition, pulsed

Matsubara et al. [126] used oxygen radical-assisted PLD to grow highly transparent and low-resistivity Al-doped ZnO films at room temperature. A KrF excimer laser (X = 248 nm, 30 ns pulse width, 10 Hz repetition rate) was used for ablation. The oxygen partial pressure during deposition was 0.7-1.4 x 10 Torr, and the applied RF power was 150W. The distance between the target and the substrate was approximately 6 cm. The minimum resistivity of the obtained transparent films was [Pg.116]

Pressure is often quoted in the non-SI units of torr, 1 torr being equivalent to 1 mmHg. The SI unit for pressure is the pascal. Pa. One Pa is equal to one newton per square meter (N/m ). To convert between torr and Pa, simply multiply the pressure in torr by 133.3 to obtain the pressure in Pa (750torr = 10 Pa). [Pg.503]

Fxcimer lasers operating in the UV are the laser of choice for most PLD systems. The operating wavelengths used in commercial systems are shown in Table 28.6. Pulse energies up to 500mJ are used with repetition rates up to several hundred hertz. [Pg.503]

Pulsed-laser deposition offers several advantages over other PVD methods [Pg.503]

Growth of films having complex stoichiometry can be achieved. [Pg.503]

The irradiation source is outside the deposition chamber allowing flexibility. Multiple chambers can [Pg.503]

DEC coating was first prepared by Aisenberg and Chabot using ion beam deposition in 1971 [2]. At present, PVD, such as ion beam deposition, sputtering deposition, cathodic vacuum arc deposition, pulsed laser deposition, and CVD, like plasma enhanced chemical vapor deposition are the most popular methods to be selected to fabricate DEC coatings.

The approaches used for preparation of inorganic nanomaterials can be divided into two broad categories solution-phase colloidal synthesis and gas-phase synthesis. Metal and semiconductor nanoparticles are usually synthesized via solution-phase colloidal techniques,4,913 whereas high-temperature gas-phase processes like chemical vapor deposition (CVD), pulsed laser deposition (PLD), and vapor transfer are widely used for synthesis of high-quality semiconductor nanowires and carbon nanotubes.6,7 Such division reflects only the current research bias, as promising routes to metallic nanoparticles are also available based on vapor condensation14 and colloidal syntheses of high-quality semiconductor nanowires.15...
