Gd4Mo4O20
Gd4Mo4O20 is a semimetallic gadolinium molybdenum oxide characterized by its complex structural nature and potential thermodynamic instability.
About Gd4Mo4O20
Gd4Mo4O20 is a complex oxide composed of gadolinium, molybdenum, and oxygen. It exhibits a near-zero-gap electronic character, placing it in the semimetallic regime, which makes it an intriguing subject for fundamental studies into the electronic behavior of rare-earth transition metal oxides.
Due to its position above the thermodynamic hull, this compound is considered potentially unstable under standard conditions. Its existence as a rare structural variant highlights the complexity of the gadolinium-molybdenum-oxygen phase space and the challenges involved in synthesizing such specific stoichiometric arrangements.
Key Properties
