About In2Na1Pb1
In2Na1Pb1 is a ternary intermetallic compound composed of indium, sodium, and lead. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that bridge the gap between conductors and semiconductors.
Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Despite this, it remains a subject of interest for researchers investigating complex phase spaces and the structural diversity of ternary systems containing alkali metals and post-transition elements.
Key Properties
