Characteristics of Semiconductors
Semiconductors are materials that have electrical conductivity between that of conductors and insulators. They are used extensively in electronics, ranging from microprocessors in computers to solar cells in renewable energy systems. Understanding the characteristics of semiconductors is crucial for engineers and scientists working in semiconductor research and development.
- Bandgap: One of the most important characteristics of semiconductors is their bandgap. The bandgap is the energy difference between the valence band (the highest occupied energy level) and the conduction band (the lowest unoccupied energy level). Semiconductors have bandgaps in the range of 0.1-2.0 electron volts (eV), which allows them to absorb and emit light that falls within this range.
- Doping: Doping is the process of intentionally adding impurities to a semiconductor to alter its electrical properties. This is done by introducing atoms that have one more or one less electron than the semiconductor atoms. The added impurities create either excess or deficiency of electrons in the semiconductor, which can then be used to control the conductivity of the material.
- Carrier Mobility: Carrier mobility is a measure of how easily charge carriers (electrons or holes) move through a material under an external electric field. Semiconductors have lower carrier mobility than conductors due to their crystalline structure and impurities, but higher than insulators due to the presence of charge carriers.
Semiconductors are also characterized by their unique optical and thermal properties. They have a high refractive index, which makes them useful in optoelectronic devices such as LEDs and lasers. They also have a high thermal conductivity, which is important in designing semiconductor devices that can dissipate heat efficiently.

History of Semiconductors
When we think about semiconductors, it is likely that most of us are probably familiar with their role in powering modern electronics. However, the story of semiconductors goes back much further than the development of smartphones and computers. In this section, we will dive into the history of semiconductors and explore how this industry has evolved over time.
The history of semiconductors can be traced back to the early days of electricity, when scientists began to experiment with materials such as selenium and germanium, which were found to exhibit some of the unique properties that are now associated with semiconductors. However, it wasn’t until the mid-20th century that semiconductors began to be widely used in electronics.
Today, the semiconductor industry is a crucial part of the global economy, driving the development of new technologies and powering everything from smartphones to electric vehicles. Let’s take a closer look at some of the key events that have shaped the history of semiconductors:
- 1947: The invention of the transistor, which is widely regarded as one of the most important discoveries in the history of electronics. Developed by John Bardeen, Walter Brattain, and William Shockley at Bell Labs, the transistor revolutionized electronics by providing a more efficient way to amplify and switch electronic signals.
- 1958: The development of the integrated circuit, which allowed multiple transistors to be housed on a single piece of semiconductor material. This marked a major breakthrough in the development of electronics, as it allowed for the creation of much smaller and more powerful devices.
- 1965: Gordon Moore, co-founder of Intel Corporation, made a now-famous prediction that the number of transistors housed on a single integrated circuit would double every 18-24 months. This prediction, which has come to be known as Moore’s Law, has held true for several decades and continues to drive innovation in the semiconductor industry today.
As we can see, the history of semiconductors is closely tied to the development of electronics and the constant drive to create smaller, more powerful devices. Today, the semiconductor industry plays a vital role in powering the modern world, and we can expect to see continued innovation and growth in this sector in the years to come.
Types of Semiconductors
Semiconductors are materials that have properties of both conductors and insulators. They can conduct electricity, but not as well as metals, and they can resist electricity, but not as well as insulators. These properties make semiconductors essential components of electronic devices like transistors, diodes, and integrated circuits. There are two main types of semiconductors: intrinsic and extrinsic.
Intrinsic Semiconductors
- Intrinsic semiconductors are made of pure materials, such as silicon and germanium.
- They have equal numbers of electrons and holes, which creates a balance in their conductivity.
- At room temperature, they have a low level of conductivity, but their conductivity increases at higher temperatures.
Extrinsic Semiconductors
Extrinsic semiconductors are made by adding impurities to an intrinsic semiconductor, which changes its electrical properties. The two types of extrinsic semiconductors are:
- N-type: impurities like phosphorus or arsenic are added to create a semiconductor with more electrons than holes. This results in a negative charge, hence the name N-type.
- P-type: impurities like boron or aluminum are added to create a semiconductor with more holes than electrons. This results in a positive charge, hence the name P-type.
Doping Concentration in Extrinsic Semiconductors
The electrical properties of extrinsic semiconductors depend on the concentration of impurities, which is referred to as doping concentration. Too much doping can lead to a reduction in the semiconductor’s ability to conduct electricity, while too little doping can result in low conductivity.
| Doping concentration | Type of semiconductor | Conductivity |
|---|---|---|
| Low | Extrinsic | Low |
| Low | Intrinsic | Low |
| High | Extrinsic | High |
Extrinsic semiconductors with high doping concentrations are used in applications that require high conductivity, such as power electronics and solar cells, while those with low doping concentrations are used in applications that require more control over the flow of electricity, such as microprocessors and memory chips.
