ErTlSe2 is a ternary ceramic compound combining erbium, thallium, and selenium elements. This is a research-phase material studied primarily in semiconductor and optoelectronic contexts rather than an established commercial ceramic. The material family exhibits potential for infrared applications and narrow-bandgap electronic devices, though industrial adoption remains limited; researchers are investigating its thermal, electrical, and optical properties to assess viability against more mature alternatives like cadmium telluride or lead chalcogenides.
