Thermal characterization of nano-featured devices is a critical challenge for the development of high performance devices. Although far-field thermoreflectance imaging is limited in spatial resolution by the optical diffraction limit, it is more amenable to absolute temperature calibration of plasmonic devices than existing near-field scanning probe tip methods. We have built an advanced thermoreflectance...
As the size of electric and optoelectronic devices is reduced to nanoscale, self-heating becomes a major reliability concern. Leveraging designs that could intrinsically remove or reduce the heat and in turn decrease temperature is desirable. In this work, twin nanoscale heater lines with four-probe electrical measurement combined with full-field thermal imaging are used to elucidate the departure...
Thermoreflectance thermal imaging technique uses light in the visible wavelength range and has a diffraction limit of ∼250nm. Despite that TR is still capable of acquiring temperature signal from devices smaller in size down to ∼3x below diffraction limit. Below diffraction limit, the detected thermoreflectance signal underestimates the true measured temperature by 360%. Image blurring was used in...
