(vi) With reference to the Fig. Qla below, indicate the statements(s) which are True [3 marks) 0.015 10 1.2 100 0.33 Transmission (%) Dopant Concentration [x 1018 cm) 0.1 Si indirect bandgap 0.01 7.3 1.0 1.5 2.0 2.5 Wavelength (um) Fig. Qla (a) Light wavelength below that of equivalent Si bandgap is absorbed abruptly by silicon substrate. [True/False] (b) Light transmission through silicon substrate is affected by dopant concentration. The higher the concentration, the lower is the light absorption. [True/False) (c) At very low dopant concentration, the transmission across wavelength is almost similar [True False)
