“…The samples we studied are nano-CdSe photoconductors [ 1 , 76 , 77 ] and the nano-Si-SiO 2 composites [ 3 , 22 , 75 ] on which we conducted optical [ 3 , 9 ], electrical [ 15 , 76 ], and nanospectroscopy [ 11 , 77 ] measurements. In [ 77 ], we detailed our results on nano-CdSe, and in [ 3 , 9 , 40 , 76 , 79 ], we detailed our results on nano-Si-SiO 2 . Here, we mention that such systems have already been shown to result in quite a few optoelectronic applications [ 5 , 13 ], the conspicuous of which are quantum dots [ 50 , 63 , 80 , 81 , 82 , 83 ] and quantum well [ 47 , 48 , 58 , 84 , 85 ] devices.…”
