Probing Semiconductor‐Semiconductor Interfaces
Physics Today 40 (1), 26–34 (1987);
https://doi.org/10.1063/1.881110
Synchrotron radiation studies are shedding light on the theoretically complex regions between different semiconductors, bringing closer the goal of predicting band structures at the meV accuracies necessary for device applications.
Asymptotic Freedom
Physics Today 40 (1), 39–44 (1987);
https://doi.org/10.1063/1.881111
The force between quarks varies with the distance between them: The dynamics of the vacuum enhance the force at large distances, while at short distances the interaction grows weaker.
Icosahedral Boron‐Rich Solids
Physics Today 40 (1), 55–62 (1987);
https://doi.org/10.1063/1.881112
The unusual three‐center bonding and unique crystal structures of these refractory materials produce many exceptional properties: Some compounds are, for example, very high‐temperature thermoelectrics.
