FIG. 2.

Intrinsic voltage responsivity from rf heterodyne mixing measurement, along with the bolometric responsivity calculated from Eq. (1). (a) Data at , along with the experimental noise floor. (b) Data at . The larger input power used at results in the discrepancy between the measured and calculated responsivities near zero bias current. The noise floor (not shown) is below the data.
