XRD reveals that the germanium electrodeposits are of crystalline structure and have the preferred crystallographic growth orientation [220]. The presence of the hydrogen bonding in the germanium films such as Ge-H and Ge-H-2 is shown from the IR absorption and does not cause a phase transition from crystalline structures to amorphous structures. The AFM images exhibit anomalous surface roughening behaviors in growth that deviate from statistical surface growth models and indicate a transition from rough surfaces to smooth surfaces., 論文}, pages = {101--105}, title = {Evaluation of crystalline germanium thin films electrodeposited on copper substrates from propylene glycol electrolyte}, volume = {162}, year = {2003} }
