Isotropic silicon etch characteristics in a purely inductively coupled SF6 plasma (2019)
Journal Article
Panduranga, P., Abdou, A., Ren, Z., H. Pedersen, R., & P. Nezhad, M. (2019). Isotropic silicon etch characteristics in a purely inductively coupled SF6 plasma. Journal of Vacuum Science and Technology B, 37(6), https://doi.org/10.1116/1.5116021

The characteristics of isotropic etching of silicon in a purely inductively coupled SF plasma are quantitatively studied. Since the etch results are strongly dependent on mask features, the authors investigated both large area and narrow trench etch...

On the measurement of the Pockels effect in strained silicon (2015)
Journal Article

We measure the voltage-dependent phase shift in silicon waveguides strained by a silicon nitride layer and show that, in our measurements, the phase shift is due to free carrier accumulation inside the waveguides. Nonetheless, inverting the applied v... Read More about On the measurement of the Pockels effect in strained silicon.
