Question
Which of the following cannot be used in electronic devices?
✓

Answer

  1. Quasicrystals.
Explanation:
Aluminum gallium arsenide, indium gallium arsenide, and gallium arsenide are used in Laser diodes, LEDs, whereas Quasicrystals have poor heat conductivity which makes them good insulators, so not used in electronic devices.
