摘要
The newly introduced setup for 'absolute' constant photocurrent method allows measurement of the optical (photocurrent) absorption spectrum, alpha(E), directly in absolute units (cm(-1)) without additional calibration and undisturbed by interference fringes, Computer simulation was performed to demonstrate the precision of the measurement and to explain residual interferences sometimes observed. The residual interferences are shown to be direct fingerprints of an inhomogeneous defect distribution.
