Used RIBER 32 #293628863 for sale

Molecular beam epitaxy (MBE) is a thin-film deposition technique used to create thin layers of single crystal material. RIBER 32 is a highly reliable, computer-controlled equipment made for the production of semiconductor structures. It is equipped with up to 1-10 molecular beams of different materials and offers impressive data collection powers. This system is ideal for precision molecular beam epitaxy (MBE) growth of complex structures. 32 consists of a UHV chamber and several effusion cells, arranged in a hexagonal geometry around the sample holder. The chamber is connected to a turbo molecular pump, a mechanical pump, as well as an ion pump for purging the chamber of atmospheric gasses. In order to create the various layers of semiconductors which form the basis of a semiconductor device, multiple effusion cells for reactive gases, such as source materials and dopants, are connected to the chamber. The unit's operating temperature ranges between 100 - 1,200°C and is adjustable from the main control computer. The chambers on RIBER 32 machine can be equipped with a variety of accessories and instruments to monitor the growth process. For example, a quartz microbalance can be used to control the thickness of the sample while a Reflection High-Energy Electron Diffraction (RHEED) tool can be used to visually observe the structure and progress of the sample in real time. Mass Spectrometry can also be used to measure the concentration of different species in the chamber. 32 asset is a powerful MBE growth tool capable of producing high-quality structures with minimal defects. The computer-controlled setup allows users to quickly adjust parameters such as pressure, temperature, and compositions. This helps in producing desired films for varying device requirements on a consistent basis. Additionally, the high versatility of RIBER 32 model makes it suitable for producing materials for a wide variety of applications, from optoelectronics to energy storage.
