2016년 6월 16일 1. In gallium arsenide. a) Find the energy of an exciton that is formed from an electron and a hole. b) Find the exciton radius in the ground state of an exciton. Hint: The ionization energy (E) for a hydrogen atom and the Bohr radius (ao) are given by E= -mq and a= 4megh² mq² Segh² Explain wh
