Discussion Overview
The discussion centers on calculating the fringe field component parallel to the SiO2 surface at the edge of a small metal electrode in an asymmetrical parallel plate capacitor. The context includes theoretical considerations and calculations related to electric fields in capacitors.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant describes a scenario involving an asymmetrical parallel plate capacitor with a significantly larger bottom electrode and seeks to calculate the fringe field at the edge of a small metal electrode.
- Another participant suggests that the bottom electrode can be approximated as an infinite plane and proposes using an image electrode method to simplify the calculation.
- A clarification is requested regarding the thickness used in the calculation, initially stated as 6 nm but later corrected to 600 nm.
- There is a question about whether the calculated field thickness refers to vertical or horizontal dimensions, with a specific interest in the horizontal fringe field.
- A participant notes that calculating the fringe field is complex but suggests using the fringe field of a symmetric capacitor with the corrected thickness of 600 nm between the plates.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the specifics of the calculation method or the interpretation of the thickness, indicating that multiple views and uncertainties remain in the discussion.
Contextual Notes
The discussion involves assumptions about the geometry of the capacitor and the applicability of the infinite plane approximation, which may not hold in all scenarios. The exact nature of the fringe field calculation remains unresolved.
