Semiconductor
Who invented semiconductor?
Karl Braun in 1874.
What is the effect of heating on resistance of Semiconductor?
The resistance will decrease.
Highlight some advantages of Semiconductor devices?
Semiconductor devices are small in size, its low power consumption, higher reliability, fast switching speed, and ease of integration, making them the foundation of modern electronics and technology.
What recent advancements have impacted Semiconductor technology?
Some recent developments include the use of wide-bandgap semiconductors (like SiC and GaN) for power electronics and the exploration of novel materials, such as perovskite, for high-efficiency solar cells. Hence semiconductors are continuously evolving over time in form of there fabrication methods, device design etc.
