  A new project on crystalline defect science maned “singularity project” has started from the fisical year 2016. Traditionally, any disorders found in crystals have been regarded as structural defects that ought to be eliminated from the materials. However, the singularity project is trying to introduce a Copernican revolution in this notion: it aims to focus on imperfect crystals which contain intentionally introduced defects. Furthermore, we try to fabricate functional electronic devices that cannot be achieved with conventional perfect crystals by having these devices take advantage of the versatile physical properties of defects. In this volume, several members of the singularity project show the newst results on widegap semiconductors, which are the exellect materias to test our new idea on crystalline defects.
