    摘要: Described is a radiation-emitting semiconductor body (1) with an active layer (2) for generation of radiation of a first wavelength (λ1) and a reemission layer (3) which comprises a quantum well structure (4) comprising a quantum layer structure (5) and a barrier layer structure (6). The reemission layer is intended for generation of incoherent radiation of a second wavelength (λ2) by absorption of the radiation of the first wavelength in the barrier layer structure.

    摘要: A stacked bulk acoustic resonator includes a first piezoelectric layer stacked on a first electrode, a second electrode stacked on the first piezoelectric layer; a second piezoelectric layer stacked on the second electrode, and a third electrode stacked on the second piezoelectric layer. The stacked bulk acoustic resonator includes further includes an inner raised region formed in an inner portion on a surface of at least one of the first, second and third electrodes, and an outer raised region formed along an outer perimeter on the surface of the at least one of the first, second or third electrodes. The outer raised region surrounds the inner raised region and defines a gap between the inner raised region and the outer raised region.
