Product Details
Germanium (Ge) is an element on the periodic table of elements. Its Atomic number is 32, and it exists in nature in a very low content. Single crystal germanium has a cubic structure, where each germanium atom is surrounded by four equidistant germanium atoms, forming a very stable structure. This structure enables germanium single crystals to have excellent electrical and optical properties.
Germanium single crystal has several important performance advantages. Firstly, it has a high carrier mobility, and the electron and hole mobility of germanium is higher than that of silicon, which allows for higher speeds in specific applications such as high-speed electronic devices. Secondly, germanium has good optical properties, moderate band width, and can absorb and emit light within a certain range, especially in the infrared region. This makes germanium widely used in fields such as optoelectronics and fiber optic communication. Finally, compared to silicon, germanium has a wider operating temperature range, which makes it potentially useful in certain devices that require extreme temperature operation.
Single crystal germanium is widely used in high-speed electronic devices, and its high carrier mobility is very suitable for such devices. In the field of optoelectronics, the optical properties of germanium make it an important material. In addition, germanium alloys are also used as thermoelectric materials, which can convert between thermal and electrical energy.
The application prospects of germanium single crystals are broad, but due to their low content in the crust and high mining costs, how to effectively improve the utilization efficiency and recovery rate of germanium is an important direction for the development of germanium single crystals in the future. Meanwhile, with the progress of science and technology, we can foresee that the application of germanium in new energy, nanotechnology, semiconductor technology, optoelectronics and other fields will be more extensive.
