It Can be observed from Figure 3 that the Diameter of Ablated Area on the surface of all samples is Film About
400 Chemically Linked. Furthermore, the Penetration depth deposited on the surface for 3 H Film looks darker than those of 1
and H 2. It indicates that the depth Penetration deposited on the surface for 3 Film is deeper than those of H 1 and
H 2. This is confirmed by the increase of from 0.7 to 1.4 mg Lost Target mass ablation with increasing time from 1
to 3 H. The rate of mass Target Lost and Found was determined to decrease from 11.7 × 7.8 × 10-3 to 10-3 mg / min.
This is Due to the decrease in density after working for the Energy Laser Longer time.
Figure 4 shows the cross. -section morphology of the TE Films obtained from the Laser ablation for 1, 2 and 3 H.
The Thickness of the TE Films was estimated from the images and the results are in Table 1. It is seen GIVEN that
the Thickness of the TE Films. increases from 35 to 58 when the ablation time is increased from 1 to 3 h. In addition,
the deposition rate of the TE and Found Film was determined to decrease from 5.8 to 3.2 Å / min. The results
are in Agreement with the Target mass Lost results.
For the Films with a Thickness of About 50 NM (Figure 4 (a) and Figure 4 (B)), the columnar growth of the
Films was observed.
Figure 5 shows the surface. morphology of the TE films. It Can be observed that the morphology of all the TE
Spherical Shape Films is mostly not. The particle Size Distribution of the TE particles could be obtained by measuring
the total Size of particles of particles in the FE-200 About SEM image using the Image J Program. The
plots of the particle Size Distribution of the TE particles are shown in Figure 6.
As seen in Figure 6, the particle Size of the TE particles obtained from the Laser ablation for 1, 2 and 3 are H
ranged from 15 to 35, 15. to 45 and 20 to 55 nm, respectively. The average particle Size of the TE particles is
Summarized in Table 1.
The average particle Size of the particles as shown in Table 1 TE revealed that the particle Smallest Size of the
TE particles was obtained from a Laser ablation of 1 H and Found to be. 28.4 NM with the Narrow particle Size Distribution
in the Range of 15 to 35 NM. It is seen that the particle size increases with increasing ablation time. It
should be Pointed out that all of the TE particles Films prepared in this Work are nanoparticles.
The crystalline structure of the prepared Films TE was investigated by XRD. Figure 7 shows the XRD Patterns
of the TE Films deposited with different pulsed CO2 Laser ablation times. XRD Patterns of the P-Type
Bi0.45Sb1.55Te3 Films were compared with those of P-Type and P-Type Material Bi0.45Sb1.55Te3 bulk Bi0.5Sb1.5Te3
Material Number according to JCPDS card from 49 to 1,713. It is seen that Two Dominant Peaks, (015) and (the 1,010th), are
observed in all the deposited Films. Result of this is that in accordance with JCPDS card Number from 49 to 1713.
However, the Intensity of (015) Peak of TE Film deposited for 3 H is greater than those of H 2 and 1. This is Due
to the Thickness of 3 H-Film is deposited thicker than those of h-1 and H-2 Films deposited.
