Compositionally graded combinatorial films have been characterized by a high throughput automated spectroscopic reflectometer. The data from this instrument were used to map the thickness and index of refraction of the compositionally varying films. Combinatorial films produced by dual-beam, dual-target pulsed laser deposition and characterized with the reflectometer include the BaTiO3–SrTiO3 s...

Phase transformation of thin film (∼30 nm) In2Se3/Si(111) (amorphous → crystalline) was performed by resistive annealing and the reverse transformation (crystalline → amorphous) was performed by nanosecond laser annealing. As an intrinsic-vacancy, binary chalcogenide semiconductor, In2Se3 is of interest for non-volatile phasechange memory. Amorphous InxSey was deposited at room temperature on S...

introduction: laser pointers are devices that produce a weak laser beam of 630-680 nmwavelength and 1-5 mw power (classii or iii a laser). these devices generally emit a redbeam that is used by lecturers and teachers for presentations. some children use pointers astoys and sometimes direct the beam to their own or others' eyes. material and methods: following irradiation by a laser pointer beam...

A pre-annealing atmospheric pulsed laser exposure was applied to decrease the phase transition (from chemically disordered A1 phase to chemically ordered L10 phase) temperature of FePt nano-particles on a Si (100) substrate. Different pre-annealing laser energy densities of 0.024 and 0.079 J/cm were utilized to expose the pulsed laser deposition (PLD) FePt thin film samples under atmospheric co...

The effect of the crystallization and activated annealing of Si films using an excimer laser and the new CW blue laser are described and compared with furnace annealing for application in advanced TFTs and for future applications. Pulsed excimer laser annealing (ELA) is currently being used extensively as a low-temperature poly-silicon (LTPS) process on glass substrates as its efficiency is hig...

Introduction: In laser surgery, the laser beam can evaporate and cut the tissue like a small surgical knife when the tissue temperature is heated to 100 degrees Celsius. a complete understanding of the distribution of damage in both pathologic tissue and surrounding tissue is necessary. Although the test is the most realistic solution for treating medical problems, for this rea...

In this paper, we have reported birefringence manipulation in regenerated high birefringent fiber Bragg grating (RPMG) by using CO2 laser annealing method. The results indicate that the birefringence of RPMG remains unchanged after CO2 laser annealing followed by slow cooling process, but reduced after fast cooling process (~5.6×10-5). After a series of annealing procedures with different cooli...

Excimer laser annealing studies were conducted of SrBi2Ta2O9, Pb(ZrxTi1-x)O3 and CeMnO3 thin films. The main incentive was to develop a low temperature process for SrBi2Ta2O9 thin films, which typically require a 750 C anneal to crystallize and achieve optimum ferroelectric properties. The results show that room temperature laser annealing can crystallize SrBi2Ta2O9, with a strong (200) preferr...

Pressure media are one of the most effective deterrents of pressure gradients in diamond-anvil cell (DAC) experiments. The media, however, become less effective with increasing pressure, particularly for solid pressure media. One of the most popular ways of alleviating the increase in pressure gradients in DAC samples is through laser annealing of the sample. We explore the effectiveness of thi...
