Visible and Near-infrared Microdisk Resonators on a 4H-Silicon-Carbide-on-Insulator Platform

Suppression of the forward voltage degradation is essential in fabricating bipolar devices on silicon carbide. Using a highly N–doped 4H–epilayer as an enhancing minority carrier recombination layer is a powerful tool for reducing the expansion of BPDs converted at the epi/sub interface; however, these BPDs cannot be observed by using the near–infrared photoluminescence in the layer. Near–ultraviolet photoluminescence was instead used to detect BPDs as dark lines. In addition, a short BPD converted near the epi/sub interface and contributing to the degradation was detected. When this evaluation was applied to the fabrication of a pin diode including a highly N–doped 4H–epilayer, the Vf shift was suppressed in comparison with that in a diode without the layer.

Dependent Density

Molecule-sized fluorescent emitters are much sought-after to probe biomolecules in living cells. We demonstrate here by time-dependent density functional calculations that the experimentally achievable 1-2 nm sized silicon carbide nanocrystals can emit light in the nearinfrared region after introducing appropriate color centers in them. These near-infrared luminescent silicon carbide nanocrystals may act as ideal fluorophores for in vivo bioimaging.

We will review recent demonstrations of single photon emission in different silicon carbide (SiC) polytypes, in both bulk and nano-structured form. Due to well established doping, and micro- and nanofabrication procedures deep defects photoluminescence (PL) can be electrically excited and incorporated in SiC nanomaterials. Finally we will report on preliminary results to incorporate near infrared defects in SiC nanoparticles.
