Bandgaps

As Painter notes, there has been a rich history of research into both photonic and phononic crystals, which use tiny energy traps called bandgaps to capture quanta of light or sound within their structures. ❋ Unknown (2009)

Strano's team built, for the first time, a fibre made of two layers of nanotubes with different electrical properties - specifically, different bandgaps. ❋ Unknown (2010)

"The main reason that our unique alloy nanowires could potentially improve the efficiency of photovoltaic (PV) cells is the fact that we can produce a wide range of bandgaps that match the entire spectrum of sun light," Ning said. ❋ Dana Sheaff (2010)

In a nutshell, bandgaps have to do with how electrons behave and what it takes to get them excited. ❋ Unknown (2010)

Sets of states that are not possible form regions between those bands, and these are called bandgaps. ❋ Unknown (2010)

Amorphous silicon's bandgaps depend on how the substance is alloyed and can range from ❋ Unknown (2010)

Silicon's light absorption properties are determined by its direct and indirect bandgaps. ❋ Unknown (2010)
