We achieved the crystal growth of a large grained InGaAs film (> 100 μm) on glass and plastic film using a Ge seed layer formed by Al-induced layer exchange. The resulting InGaAs layer exhibited the near-infrared photoresponsivity. These values are the largest among the InGaAs films directly grown on insulators.
