A comparative study of SiC epitaxial growth in vertical hotwall CVD reactor using silane and dichlorosilane precursor gases

Tawhid Rana, MVS Chandrashekhar, Haizheng Song +1

SiC epitaxial films grown in an inverted chimney CVD reactor are analyzed and compared for growth rates, doping concentration and surface morphology using silane-propane-hydrogen a…

Study of epitaxial graphene on non-polar 6H-SiC faces

B. K. Daas, K. Daniels, S. Shetu +2

We present epitaxial graphene (EG) growth on non-polar a-plane and m-plane 6H-SiC faces where material characterization is compared with that known for EG grown on polar faces. Ato…

Polariton Enhanced IR Reflection Spectra of Epitaxial Graphene on SiC

B. K. Daas, K. M. Daniels, T. S. Sudarshan +1

We show ~10x polariton-enhanced infrared reflectivity of epitaxial graphene on 4H-SiC, in SiC's restrahlen band (8-10um). By fitting measurements to theory, we extract the thicknes…

Doping Dependence of Thermal Oxidation on n-type 4H-SiC

B. K. Daas, M. M. Islam, I. A. Chowdhury +3

The doping dependence of dry thermal oxidation rates in n-type 4H-SiC was investigated. The oxidation was performed in the temperature range 1000C to 1200C for samples with nitroge…

Ultrafast Relaxation Dynamics of Hot Optical Phonons in Graphene

Haining Wang, Jared H. Strait, Paul A. George +8

Using ultrafast optical pump-probe spectroscopy, we study the relaxation dynamics of hot optical phonons in few-layer and multi-layer graphene films grown by epitaxy on silicon car…
