Aluminum. There is a well-known interband transition in aluminum near 800 nm illumination,19 which corresponds to the only substantial absorption peak near the visible spectrum suitable for thermoreflectance imaging. In this study, we examined the aluminum heater line under 780 nm illumination, for applied biases similar to that of the gold heater line due to their comparable electrical resistivities. ΔT2ω also varied similarly for the maximum applied voltage; from 3.7 K at room temperature to 8.1 K at 600 K. The reflectivity response of aluminum is positive for both bare and passivated regions, corresponding to a positive CTR which decreases over the temperature range. The passivation layer at this wavelength had the overall effect of decreasing the thermoreflectance response, more so with increasing temperatures. The CTR values for bare and passivated aluminum heater line are plotted in Figure 9. The temperature response of interband absorption in aluminum is characterized by broadening and shifting of the peak toward lower energy, largely induced by lattice volume dependence of the pseudopotential.19,21 Such a shift would decrease the magnitude of CTR (Figure 3).The higher rate of change in CTR with temperature is attributed to the larger thermal expansion coefficient of aluminum relative to the other metals. FIG. 9: The trend of the coefficient of thermoreflectance for bare and passivated aluminum. CTR shifts at a rate of about 0.22 x 10-4 per 100 K temperature change for bare aluminum, which is quite substantial considering the small values of CTR.
