Despite the lower charge carrier mobilities for low electric fields SiC outperforms Si concerning all other properties.
The wide band gap, large breakdown field and high saturation drift velocity make SiC an ideal candidate for high-temperature, high-power and high-frequency electronic devices exhibiting high efficiency.
In addition the high thermal conductivity enables the implementation of small-sized electronic devices enduring increased power densites.

+Negligible junction leakage currents at elevated temperatures due to the high band gap allow high-temperature operations without excessive leakage.
+Even non-volatile dynamic random access memory (DRAM) at room temperature can generally be realized by SiC based electronics~\cite{}.
+Additionally the wide band gap allows SiC to be used in UV detectors.
+The high saturation electron drift velocity provides higher currents and higher cut-off frequencies for SiC based high-frequency and high-power devices, such as microwave devices.
+The high breakdown strength enables the realization of electronic switching devices enduring high power densities.

Despite high-temperature operations the wide band gap also allows the use of SiC in optoelectronic devices.
Indeed, a forgotten figure, Oleg V. Losev discovered what we know as the light emitting diode (LED) today in the mid 1920s by observing light emission from SiC crystal rectifier diodes used in radio receivers when a current was passed through them~\cite{losev27}.
Apparently not known to Losev, Henry J. Round published a small note~\cite{round07} reporting a bright glow from a SiC diode already in 1907.
However, it was Losev who continued his studies providing comprehensive knowledge on light emission of SiC (entitled luminous carborundum) and its relation to diode action~\cite{losev28,losev29,losev31,losev33} constituting the birth of solid-state optoelectronics.
And indeed, the first significant blue LEDs reinvented at the start of the 1990s were based on SiC.
Due to the indirect band gap and, thus, low light emitting efficiency, however, it is nowadays replaced by GaN and InGaN based diodes.
-However, even for GaN based diodes SiC turns out to be of great importance since it constitutes an ideal substrate material for GaN epitaxial layer growth~\ref{liu02}.
-In doing so, the 3C polytype promises good quality, single crystalline GaN films~\ref{takeuchi91,yamamoto04,ito04}.
