Li2 Al2 P4 K4
semiconductor· Li2 Al2 P4 K4
Li₂Al₂P₄K₄ is a mixed-cation phosphide semiconductor compound combining lithium, aluminum, potassium, and phosphorus. This is a research-phase material rather than an established commercial compound; it belongs to the broader family of multi-element phosphide semiconductors being explored for optoelectronic and photovoltaic applications. The incorporation of multiple light elements (Li, K) alongside transition-capable Al and P suggests potential for tunable bandgap properties and ion-conducting pathways, making it a candidate for next-generation energy storage or thin-film photovoltaic research.

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.
