Resonant Raman scattering intensities from nanoscale films of pentacene display large resonant enhancements that enable observation of vibrational modes in monolayer cluster films.
Recent developments in semiconductor growth techniques have made possible a new class of materials in which alternating thin layers of two different semiconductors form an artificial superlattice.
