Semi conductor materials:
Elemental semiconductors-Silicon, Germanium
Binary semiconductors-Aluminium, gallium, indium, phosphorus, arsenic, antimony
Ternary semiconductors-Aluminum, Gallium, Arsenic
Quaternary Semiconductors-Indium, Gallium, Phosphorous, Arsenic
Why Opto-electronics sensor system used:
● The sensors used in an automotive environment must be reliable
● Produce exactingly accurate results
● Require little maintenance
● Help reduce overall system cost and extend the life of the system or sub system unit
● Integrated optoelectronic sensors are non-contact sensors, that is, they are able to perform their sensing or measurement functions without the need for physical contact with other parts of the system or sub-system
Advantages:
● Reducing the number of required components
● Improving the reliability of the system or sub-system
● Improving the styling, aesthetics and ergonomics of the overall vehicle through better utilization of the available space
● Improving the manufacturability of the vehicle by reducing the number of sensors that need to be positioned during production
Disadvantages:
● They are not giving any direct feedback
