Extract of sample "Chemical Vapor Deposition Grown Transparent Conducting Oxides"

Conclusions This project relied on the preparation of thin film TCOs that possessed favorable electrical properties and optical properties. The electrical properties were determined using measurements from 4PP as well as through Hall Effect measurements that were aided by thickness measurements from Dektak. The results show that samples AGC-U and TEC 8 are both fit for use as semiconductor materials though the electrical conductivity of TEC 8 is better than that for AGC-U. Moreover when it comes to samples 198-219 the electrical properties (such as sheet resistance, mobility, resistivity and carrier concentration) tend to change as the doping levels are varied.

The best electrical properties can be attributed to Sample 200 (with a doping level of 0.6 M) as it has the highest conductivity. It was also found out that fluorine doped samples had higher resistivity and that the mean transmission and mean reflection change as the doping levels of fluorine are changed. The mean transmission varies between 46.95% and 63.21% while the mean reflection varies between 2.21% and 4.25%. Sample 198 had the highest transmission while Sample 213 had the lowest transmission and reflection.

It was also found out that the peak position did not vary as the levels of fluorine doping were changed. However the intensity (Lin count) tends to change as fluorine doping levels are changed. Sample 213 (0 M) had the lowest intensities while Sample 198 (0.4 M) had the highest peak. In relation to samples 235 to 242 it was found out that the electrical properties and the optical properties tend to change as the ratio of tin to water and the number of passes changes. The mean transmission levels vary between 33.3% and 50.53% while the mean reflection levels vary between 2.36% and 6.34% with Sample 237 having the highest transmission.

It was also found out that the peak position did not change as the ratio of tin to water changed but it stayed within the same two theta limits. However the intensity (Lin count) tends to change as the tin to water ratio changes. Sample 239 had the lowest intensities while Sample 231 had the highest peak.
