Discussion Overview
The discussion revolves around the photoelectric effect in pure metals compared to metals connected at one end with another metal. It explores whether the work function of the metal exhibiting the photoelectric effect changes in the latter scenario, with implications for solid state physics and condensed matter.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant questions the difference in the photoelectric effect between a pure metal and a metal connected to another metal, specifically regarding changes in work function.
- Another participant notes that there is a contact potential difference between two metals with different work functions, but emphasizes that the change in work function is abrupt and that the bulk material's work function remains unchanged.
- A participant mentions methods to lower the effective work function, such as cesiating the surface of niobium (Nb) and tellurium (Te), suggesting these methods are more practical than using a metal-metal junction.
- There is a suggestion that the topic may not align with traditional Quantum Physics discussions, as it pertains more to solid state physics and condensed matter.
Areas of Agreement / Disagreement
Participants express differing views on the relevance and implications of the photoelectric effect in the context of metal junctions, with no clear consensus reached on the initial question regarding work function changes.
Contextual Notes
The discussion highlights the complexity of work function behavior at metal junctions and the potential limitations of applying concepts from Quantum Physics to this scenario. The assumptions regarding the abrupt change in work function and the lack of a depletion zone are noted but not resolved.
