|Judul||:||DEVELOPMENT OF LITHIUM TANTALITE (LITAO3) FOR AUTOMATIC SWITCH ON LAPAN-IPB SATELLITE INFRA-RED SENSOR|
Automatic switch is a deadly being animate or automatically an electrical device that use the technology sensors to detect movement, or body temperature that was detected in the switch. The sensor use is the passive infra-red receiver (PIR) by using lithium tantalite (LiTaO3) that would have capturing a moment in response temperature change. In this research, it has synthesized a thin film of lithium tantalite (LiTaO3) on a substrate silicon p-type. The film is produced by chemical solution deposition (CSD) and engineering spin coatings and temperature annealing on 550°C, 600°C, 650°C, 700°C, 750°C and 800°C. Setting up the speed and 3000 rpm is 30 seconds. The value of high absorbent show that the LiTaO3 film has a large number of energy of the photon. This research obtained the energy band-gap film LiTaO3 in the range 3.41-4.56 eV. The results concludes that the affect of temperatures annealed the optical properties of the film LiTaO3 as the substrate of Si (100) p-type semiconductor. The sensitivity of high intensity absorbent for energy and high value of band-gap is great and potential to be used prospectively for the automatic switch sensor on the satellite platform.
