Figure 5From: Morphological and nanostructural features of porous silicon prepared by electrochemical etchingXRD patterns of porous Si. XRD patterns (a), (b), (c) and (d) were obtained from samples 1, 2, 3 and 4, respectively. In pattern (a), the raw curve is separated into three Lorentzian peaks (1) to (3).Back to article page
