Understanding the different types of semiconductor materials and their properties is essential for designing and developing electronic devices that meet the growing demands of the industry. Gallium arsenide is a compound semiconductor material made up of the elements gallium and arsenic. GaAs has a direct band gap (1.43 eV), which makes it highly efficient for light emission and absorption. This property makes GaAs a critical material for optoelectronic devices like light-emitting diodes (LEDs) and laser diodes.
Silicon (Si) is the most commonly used semiconductor, but other materials like germanium, gallium arsenide, and more are also used in various applications.
Substituting many silicon atoms with phosphorus frees up numerous electrons that can move around the crystal.
Semiconductors can conduct electricity under preferable conditions or circumstances.
Without these substances, the world as we know it would look very different — there would be no smartphones or laptops, no rockets or electric cars. Here is a closer look at the most common raw materials used in building computers’ digital brains. It is the lowest, unoccupied band that includes the energy levels of positive (holes) or negative (free electrons) charge carriers. The conduction band possess a high energy level and is generally empty.
Importance of Semiconductors
Today, we are going to start a new tutorial series on Semiconductors. In this series, we will discuss the semiconductor components, devices, etc. in detail. We will start from the very basics and will gradually move towards complex concepts.
According to the Critical Raw Materials Alliance (CRMA), China produces roughly 60% of the world’s germanium, exporting 43.7 metric tons of the material in 2022. As Communications of the ACM notes, however, this requires a willingness to invest in developing cost-efficient mining, extraction, and refining processes. The difficulty of extracting REEs from raw materials has led many mining companies to choose not to pursue REE profits.
Silicon is the primary material due to its abundance, stability, and excellent semiconductor properties. Photolithography tools are essential for patterning circuits on silicon wafers, while CVD systems are used to deposit thin films of materials necessary for creating semiconductor layers. These components and tools form the backbone of semiconductor fabrication, enabling the production of devices like microprocessors, memory chips, and sensors. Semiconductor materials are essential in modern electronics and technology, as they are used to create transistors, diodes, and other electronic components.
Lecoq de Boisbaudran reasoned that there must be an element next to zinc, using Dmitri Mendeleev’s periodic trends as a guide.
Due to its high electron mobility, it was also the best rectifier material for the initial radars in World War II.
To increase their ability to conduct electricity, a doping process is used, i.e. the introduction of small amounts of other chemical elements into the semiconductor structure.
It also offers higher electron mobility than silicon, which makes it useful in high-speed electronic devices and microwave circuits.
Semiconductor manufacturing is a complex process that involves many technological steps. The first step is to obtain high-purity silicon, which is then formed into so-called silicon monocrystals. These monocrystals are then cut into thin plates called wafers, which form the basis for further production steps. The examples discussed above represent just a fraction of the wide array of semiconductor materials that drive today’s technological innovations. Each material has its strengths and limitations, and choosing the right one depends on the requirements of the specific application. As you can see in the above figure, there’s no Forbidden Gap in the Conductors and the Valence & Conduction Bands are overlapping.
Its crystal structure is similar to gallium arsenide, forming an excellent substrate for optoelectronic devices, and it is a common component of III-V semiconductors. Silicon is a suitable material for manufacturing integrated circuits due to its wide availability and simplicity. There are many benefits to using silicon as a semiconductor material.
Types of Semiconductors
The abundance of silicon makes it possible to create wafers of all shapes and sizes, no matter how big or small the requirement. These and other reasons make silicon the best choice for electronic devices. Zinc oxide is a versatile semiconductor, particularly useful in nanotechnology and thin-film applications. Known for its UV-blocking properties, ZnO is widely used in transparent films for display screens, solar cells, and even sunscreens. Its piezoelectric characteristics make it valuable in sensors, actuators, and acoustic devices, paving the way for wearable and flexible electronics. Its diverse applications firmly place ZnO among the most innovative examples of semiconductors.
Most Commonly Used Materials for Semiconductors
China is one of the few nations to focus on REE mining and refining, resulting in the nation producing 85 percent of the world’s supply of tungsten and molybdenum. The following semiconducting systems can be tuned to some extent, and represent not a single material but a class of materials. The primary purpose of this project is to help the public to learn some exciting and important information about electricity and magnetism.
These impurity atoms which are ready to accept bonded electrons are called “Acceptors“. The introduction of band theory happened during the quantum revolution in science. China’s stranglehold on REE production allows it to not only set prices but also wield the valuable semiconductor material as a political weapon. In 2010 China cut off all sales of REEs to Japan due to a dispute over Japan’s detention of a Chinese fishing captain. Whether China will choose to use REE exports during the ongoing US-Sino trade war is a concern.

Semiconductors are also used in the design of transistors, which are used both for fast switching and for current amplification. The group III nitrides have high tolerance to ionizing radiation, making them suitable for radiation-hardened electronics. I hope, now you have a complete understanding of Semiconductors’ electrical behavior. Germanium ores are rare — most germanium comes from coal fly ash or as a byproduct of zinc processing.
A rod is used to dip a crystal into molten GaAs, after which it is pulled out and rotated to start the process. Chemically speaking, silicon is the most popular natural semiconductor in contemporary technology. The quartz plate is a transparent, durable, and versatile component widely used in various industries.

Additionally, this lessens the impact of power fluctuations on data loss. Since the 1950s, silicon has been widely used as a semiconductor material. While germanium was one of the first three semiconductor materials to be used, other materials have since surpassed this material regarding usability.
To produce higher conduction, one can intentionally introduce impurities (typically to a concentration of one part per million host atoms) to produce an extrinsic semiconductor. This is called doping, a process that increases conductivity despite some loss of mobility. The fifth electron becomes a conduction electron that is donated to the conduction band.
