Cu native oxide thickness
WebThe thickness of native oxide was set to be 2.3 nm and was established in the separate experiment . The imperfect surface of the deposited film (the rough layer) was described based on the Bruggeman Effective Medium Approximation (EMA) model [34,35]. In this approach, the optical constants of the rough film are represented as a combination of ... WebJun 22, 2024 · The thickness of Cu2O is expected to be at least 100 microns. There is still plenty of unoxidized Cu metal inside the Cu2O, so cleaving it to perform cross-sectional SEM is not trival. It is also too thick …
