Semiconductors are materials that can conduct electricity under certain conditions. Electronics is the branch of engineering that deals with the design, development, and application of electronic circuits and devices using semiconductors.:

A brief view of its history:

The history of semiconductors and electronics can be traced back to the early 19th century:

1874: Karl Ferdinand Braun discovered the rectifier effect in semiconductors, paving the way for their use in electronic devices.
1904: John Ambrose Fleming invented the vacuum tube diode, a precursor to transistors.
1947: John Bardeen, Walter Brattain, and William Shockley invented the point-contact transistor at Bell Labs, a breakthrough that revolutionized electronics.
1958: Jack Kilby and Robert Noyce independently invented the integrated circuit (IC), packing multiple transistors onto a single silicon chip.
1960s-1970s: The semiconductor industry experienced rapid growth, leading to the development of microprocessors, memory chips, and other essential electronic components.

These advancements fueled the development of modern electronics, including computers, smartphones, and countless other devices.

Interesting facts:

LED Efficiency: Modern LEDs have become incredibly efficient, converting a much higher percentage of electrical energy into light compared to traditional incandescent bulbs.

Transistor Miniaturization: Modern transistors are so small that billions can fit on a single chip, enabling the creation of incredibly powerful and compact electronic devices.

Oscillator Synchronization: Multiple oscillators can be synchronized to create a coherent output, which is essential in many communication systems.
