Rb1.45Sb7.45Pb3.1Se15

Rb1.45Sb7.45Pb3.1Se15 is a mixed-metal selenide compound belonging to the chalcogenide semiconductor family, combining alkali metal (rubidium), metalloid (antimony), heavy metal (lead), and chalcogen (selenium) elements. This material is primarily of research interest for thermoelectric and solid-state energy conversion applications, where the complex crystal structure and mixed-valence composition are designed to scatter phonons while maintaining carrier mobility. While not yet commercialized at scale, compounds in this family are being investigated as alternatives to traditional thermoelectric materials for waste heat recovery and temperature-gradient power generation, particularly in applications requiring operation in specific temperature windows where conventional materials like Bi₂Te₃ become less efficient.
