Amorphous semiconductors are somewhat of a niche area of electronic materials. However, they are critical to a number of important applications. It would be worth spending some time studying them based on these applications alone. More significantly, these materials are very distinct in their optical and electronic nature. Understanding their properties is highly instructive in a general sense.
