· PPdSe

PPdSe is a layered two-dimensional semiconductor compound composed of phosphorus, palladium, and selenium. This material belongs to the emerging class of transition metal chalcogenides and is primarily of research interest for next-generation optoelectronic and electronic devices that leverage its layered structure and tunable band gap properties. Its weak van der Waals interlayer bonding makes it a candidate for mechanical exfoliation and integration into flexible or heterostructured devices, positioning it alongside other 2D materials like transition metal dichalcogenides (TMDs) for applications requiring atomically thin semiconductors.
