Al1As2Li1
Al1As2Li1 is an unstable, semimetallic ternary compound consisting of aluminum, arsenic, and lithium.
About Al1As2Li1
Al1As2Li1 is a ternary inorganic compound composed of aluminum, arsenic, and lithium. It exhibits a semimetallic electronic character, placing it in a regime where valence and conduction bands overlap, suggesting potential for unique charge transport properties.
As a material that sits above the thermodynamic hull, it is considered metastable or unstable under standard conditions. Its existence in structural databases highlights the complexity of the aluminum-arsenic-lithium phase space and the challenges involved in synthesizing such specific stoichiometric arrangements.
Key Properties
