The Indian nitride can accumulate a negative charge on its surface, something unusual in semiconductors like yours. Until now, only another case was known with this property, that of the Indian arseniuro.

In most semiconductors there is an area with few electrons around the surface, which means a great resistance when forming alloys with metals. However, this problem could be avoided if semiconductors enriched with electrons are produced on the surface.

Reviewing the properties of Indian nitride, researchers from the United Kingdom and the United States have found that it can have adequate conditions. In the laboratory, an accumulation of electrons has been achieved and barriers that prevent alloys have been eliminated. This greatly facilitates the manufacture of hybrid materials with metal-semiconductor alloys, being of great use in the field of optoelectronics. In the future it is intended to investigate the electronic properties of Indian nitride and its alloys.
