[IEEE 2018 IEEE International Conference on Semiconductor Electronics (ICSE) - Kuala Lumpur (2018.8.15-2018.8.17)] 2018 IEEE International Conference on Semiconductor Electronics (ICSE) - Effect of Different Metal Contact Distance and Light on Electrical Properties of Calcium Carbonate Thin Film

摘要： CaCO3 is an inorganic substance with low toxicity. Electrical properties of CaCO3 is rarely reported although it has promising potential as biosensor. Therefore it is our aim to provide information on CaCO3 electrical properties. This work described the effect of different distance of metal contact pad and also the effect of light to the electrical conductivity of CaCO3. CaCO3 thin film was prepared at 1.0M by gas diffusion method. From the results, the value of current is not affected by different distance of metal contact pad. Results showed conductivity of CaCO3 thin films were not affected by the presence of light. Therefore CaCO3 thin film conductivity is stable and suitable for wide application and further study such as for biosensor.
