Chalcogen-hyperdoped silicon shows potential applications in silicon-based infrared photodetectors and intermediate band solar cells. Due to the low solid solubility limits of chalcogen elements in silicon, these materials were previously realized by femtosecond or nanosecond laser annealing of implanted silicon or bare silicon in certain background gases.(More)
The clear understanding of exchange interactions between magnetic ions in substituted BiFeO 3 is the prerequisite for the comprehensive studies on magnetic properties. BiFe 0.5 Mn 0.5 O 3 films and BiFeO 3 / BiMnO 3 superlattices have been fabricated by pulsed laser deposition on (001) SrTiO 3 substrates. Using piezoresponse force microscopy (PFM), the(More)
