Q. |
Internal absorption in DH surface emitter Burros type LEDs is |
A. | cannot be determined |
B. | negligible |
C. | high |
D. | very low |
Answer» D. very low | |
Explanation: the larger band gap confining layers and the reflection coefficient at the back crystal space is high in dh surface emitter burros type leds. this provides good forward radiance. thus these structure leds have very less internal absorption. |
