Which material would you expect to have a greater bandgap energy between indium nitride and indium phosphide ?
To determine which material would have a greater bandgap energy between indium nitride (InN) and indium phosphide (InP), we need to know the elemental properties of both nitride and phosphide compounds.
1. Find the atomic numbers:
- Nitrogen (N) has an atomic number of 7.
- Phosphorus (P) has an atomic number of 15.
2. Determine the valence electrons:
- Nitrogen has 5 valence electrons (2s² 2p³).
- Phosphorus has 5 valence electrons (3s² 3p³).
3. Calculate the Bandgap Energy:
- In general, the bandgap energy of a material depends on the difference in energy between the valence and conduction bands.
- The bandgap energy of a compound is influenced by the electronegativity and atomic radius of the elements involved.
Since Nitrogen (N) has a smaller atomic number and smaller atomic radius compared to Phosphorus (P), we can expect that Indium Nitride (InN) would have a larger bandgap energy than Indium Phosphide (InP). This is because smaller atomic size atoms usually lead to a greater difference in energy levels between valence and conduction bands.
However, to determine the exact values, it is recommended to refer to a reliable reference source that provides specific bandgap energy values for InN and InP.
