Silicon carbide (SiC), is very difficult do use as a semiconductor due to highly mobile dislocations. These dislocations rapidly increase within the crystal, introducing levels in the bandgap, i.e it's no longer a semiconductor and ultimately the device will fail. However, if the NASA scientists have found a way to lock down the dislocations, which is done when regular silicon semiconductors are produced, there is no questions about the versatility of SiC.
