Our entry's topic is Semiconductor. In our page, we have discussed the nature of intrinsic and extrinsic semiconductors and their ways of conducting electricity. Based on this fundamental information, we further introduce various types of electronic components e.g. Thermistor, junction diode, LED, LDR, transistor etc., together with their working principles and their usefulness in modern technology. In addition, we lead the users to explore the essence of this advanced world, i.e. the logic gates. With different inputs and different combinations of these gates, the users will know the outputs of the logic circuit. By introducing the principles of semiconductors, we hope to give users a clearer and better understanding of the miracles behind the wonderful advanced world.
