· Na2 K4 As4 In2

Na₂K₄As₄In₂ is an experimental quaternary semiconductor compound containing sodium, potassium, arsenic, and indium—a mixed-metal arsenide that falls outside conventional III-V or II-VI semiconductor families. This material represents exploratory research into complex multinary semiconductors, which are being investigated for potential applications in optoelectronics and solid-state devices where unique band structures or chemical properties might offer advantages over traditional binary or ternary semiconductors. As a research compound, it is not yet established in production applications but serves as a test case for understanding how alkali metals can be incorporated into arsenide frameworks to engineer novel electronic or photonic properties.

Quality & Standards

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
