Abstract

The present invention provides a structure of a high electron mobility light-emitting transistor, which comprises: a substrate; a high mobility transistor (HEMT for short) region is arranged on the substrate; a gallium nitride light-emitting diode (GaN-LED, LED for short) region is arranged on On the substrate; wherein, both the HEMT region and the LED region have a two-dimensional electron gas layer, and the HEMT region is coupled to the LED region through the two-dimensional electron gas layer. The invention can generate light of different wavelengths, and can control the brightness of the light source in the LED area.

Description

technical field [0001] The present invention relates to a structure of a high electron mobility light-emitting transistor, especially a HEMT built-in LED structure. Background technique [0002] Aluminum Gallium Nitride / Gallium Nitride High Speed ​​Electron Mobility Transistor Field Effect Transistor (AlGaN / GaN HEMT) has extremely high advantages in high temperature, high frequency and high power applications; Because the direct bandgap of gallium nitride is 3.4eV, gallium nitride is also suitable for use in light-emitting devices. The wavelength range of light emitted by gallium nitride and its related ternary compounds It is very wide, ranging from green, blue to UV light, so light-emitting diodes of gallium nitride technology have been widely used. Contents of the invention [0003] The invention provides a structure of a high electron mobility light-emitting transistor, which solves the problem in the prior art that the brightness of the light source in the LED area c...
