A silicon thin film 2 mm thick and 1 cm square is suspended in air at 300K and illuminated with monochromatic light at 1 = 0.62mm with an incident power density of 1W/cm². The surface reflectivity (R) is 0.1. a=2x10³ cm¹, ns = 3.42, Si Eg = 1.12 eV. a. Find the absorbed incident optical power. b. Find the optical power incident at the rear surface. c. Find the reflectivity at the rear surface. d. Find the optical power exiting the sample. e. How much power is absorbed in the sample? Si Ф inc T Φ out W=2 μm
