Mechanically stretchable photonics provides a new geometric degree of freedom for photonic system design and foresees applications ranging from artificial skins
Terahertz (THz=1012 cycles per second,or T-ray) radiation sources are indispensable for mode materials science,chemical and biomedical imaging and sensing,as we
Increasing temperature is known to quench the excitonic emission of bulk silicon,which is due to thermally induced dissociation of excitons.Here,we demonstrate
