Manganese telluride is primarily used in the field of materials science, particularly in the development of advanced electronic and optoelectronic devices. Its semiconducting properties make it suitable for applications in thermoelectric materials, where it can efficiently convert heat into electricity. This characteristic is valuable in energy harvesting systems and waste heat recovery technologies.

Additionally, manganese telluride is explored for use in spintronics, a technology that leverages the spin of electrons rather than their charge for data storage and processing. Its magnetic properties contribute to the development of more efficient and compact memory devices.

In research, it is also studied for potential applications in solar cells and other photovoltaic devices due to its ability to absorb light and generate electrical current. Its unique properties make it a promising candidate for next-generation energy solutions.
