dc resistance as a function of bath temperature of nanotube sample measured with a bias current of 100 nA. Top inset: Measured dc resistance as a function of bias current at bath temperatures of 4.2 at 77 K. Bottom inset: experimental schematic for rf heterodyne mixing measurement.
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.
Responsivity calculated from the measured dc curve [Eq. (2)] as a function of bias current for the nanotube at . Also plotted is the measured responsivity.
