Types of Semiconductors

The journey of semiconductors began in the early 19th century when their unique properties were first observed. However, it wasn’t until the 20th century that semiconductors found their place in the heart of electronic devices. Initially, semiconductors were just curious materials that didn’t fit neatly into the categories of conductors or insulators. Their conductivity seemed … Read more

Energy Bands In Solids

In the early 20th century, scientists were making huge strides in understanding the quantum world. They discovered that electrons orbit the nucleus in atoms at specific energy levels, much like how planets orbit the sun. In 1928, a physicist named Felix Bloch took these quantum ideas and applied them to solids. He proposed that electrons … Read more
