Hafnium Sulfide powder is an important inorganic compound powder.
Chemical formula: HfS₂, indicates that it consists of two elements, hafnium (Hf) and sulphur (S), with a molecular weight of 242.62g/mol.
CAS No.: 18855-94-2.
Appearance: usually grey or purple powder.
Crystal Structure: Layered structure, the layers interact with each other through weak van der Waals forces.
Melting point: high, with good thermal stability.
Solubility: Insoluble in water, acids and bases.
Hole transport layer material: Hafnium Sulfide has a very high carrier mobility and high figure of merit, and its two-dimensional structure also has a high light transmittance, which make it very suitable as a material for the hole transport layer of organic solar cells.
Photodetectors: Hafnium Sulfide is a semiconductor material whose unique optical and electrical properties give it potential for application in photodetectors.
Light Emitting Diode (LED): It can be used as a light-emitting material or auxiliary material for LEDs to improve the luminous efficiency and performance stability of LEDs.
Field Effect Transistors (FETs): Hafnium Sulfide can be peeled off by the tape method or liquid phase stripping method to produce a two-dimensional material with a thickness of a few atomic layers, and this two-dimensional HfS₂ nanosheets can be used to fabricate field effect transistors.
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.
