Characterisation of laser-treated ag, al, and al/ag metal thin films deposited by dc sputtering
Aliyu Kabiru Isiyaku1, Ahmad Hadi Ali2, Nafarizal Nayan3.
Structural, optical and electrical properties of Nd:YAG pulsed laser-treated silver (Ag),
Aluminium (Al) and Al/Ag bi-layer metal thin films deposited by Direct Current (DC)
sputtering technique is investigated. Laser-metal interaction treatment as an alternative to
temperature annealing was used to treat the surface of the metal thin films. Measurements
from X-ray Diffraction (XRD) indicated an enhanced grain growth and crystallisation for the
laser-treated thin films with strong and dominant Ag diffraction peaks at (111) and (200)
crystal planes from Ag and Al/Ag films. The surface roughness of Ag and Al thin films
increased when exposed to 120 mJ laser energy as measured by Atomic Force Microscopy
(AFM). However, smooth surface and reduction in surface roughness were observed when
under-layer Al film was deposited below the Ag thin films (Al/Ag bi-layer). The bi-layer Al/Ag
film shows a reduced reflectance in most of the visible range as determined by UV-vis
spectrophotometer. Surface to volume atomic ratio of the laser-treated films increased with
a decrease in resistivity as examined by four-point probes. All the Nd:YAG laser-treated metal
films show a significant decrease in resistivity, sheet resistance and optical reflectance
indicating possible application as intermediate layer in transparent conductive oxide
(TCO/Metal/TCO) electrode for solar cell devices.
