InAs ingot is an important semiconductor material.
Structure: InAs is a compound of indium (In) and arsenic (As) with a sphalerite crystal structure.
Appearance: It has a silvery-grey metallic luster and a relatively flat and smooth surface.
Density: 5.67 g/cm³.
Hardness: about 3.5.
Melting point: The melting point of InAs is relatively low, about 942℃.
Electrical Properties:
InAs is a direct bandgap semiconductor material with an intrinsic bandgap of about 0.36 eV at room temperature.
The carrier mobility of InAs is very high, with an electron mobility of up to 33,000 cm²/(V・s), which means that electrons are transported efficiently through InAs materials, contributing to the performance of electronic devices.
High-speed electronics: Because of their high carrier mobility, Indium Arsenide can be used to make high-speed transistors and integrated circuits.
Low-power electronic devices: the low bandgap characteristics of InAs make it a promising application in the field of low-power electronic devices.
Infrared detectors: The optical properties of InAs in the infrared band make it an ideal material for infrared detectors.
Light Emitting Diodes (LEDs) and Laser Diodes (LDs): Indium Arsenide can be used as an active area material for the manufacture of infrared light emitting diodes and laser diodes. These optoelectronic devices have important applications in the fields of optical communication, optical storage and infrared illumination, etc. For example, at the infrared emitting end of optical communication, InAs – LD can provide stable and efficient infrared light signals.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
