Description

technical field

[0001] The invention relates to the field of material science, in particular to an indium phosphide bismuth material. Background technique

[0002] III-V semiconductor materials are widely used in the fields of lasers, photoelectric tubes and optical fiber communications. Among them, narrow bandgap materials have great advantages in the fields of microelectronics and optoelectronics as substrates for high-speed electronics and optoelectronic devices, and are also very suitable for vertical optical field lasers and high electron carrier transistors. Taking indium phosphide as an example, it has a narrow band gap and high semiconductor performance. However, indium phosphide also has the following disadvantages: although its band gap is very narrow, it also has a limit. That is, the band gap of indium phosphide cannot continue to be narrowed after being narrowed to a certain extent, nor can it continue to improve its semiconductor performance. Contents of th...
