Second harmonic measurement techniques provide higher resolution and cleaner planar tunneling spectra which help us to compare and contrast the electronic structure of these interesting materials. We will present planar tunneling spectroscopic data on YbB12 in the low temperature resistance plateau range and compare it to planar tunneling data taken on SmB6 [3].
