    Abstract: Embodiments of the present disclosure are directed to infrared detector devices incorporating a tunneling structure. In one embodiment, an infrared detector device includes a first contact layer, an absorber layer adjacent to the first contact layer, and a tunneling structure including a barrier layer adjacent to the absorber layer and a second contact layer adjacent to the barrier layer. The barrier layer has a tailored valence band offset such that a valence band offset of the barrier layer at the interface between the absorber layer and the barrier layer is substantially aligned with the valence band offset of the absorber layer, and the valence band offset of the barrier layer at the interface between the barrier layer and the second contact layer is above a conduction band offset of the second contact layer.

    Abstract: A semiconductor device includes a substrate, a buffer layer, a gradient layer, an active layer, a window layer, and an optical filtering layer. The substrate includes a first element and a second element. The buffer layer is disposed on the substrate. The gradient layer is formed on the buffer layer, and includes sublayers. Each sublayer includes the first, second, and third elements. For each sublayer, a lattice constant thereof is adjusted by changing a ratio of the second element to the third element. The active layer is formed on the gradient layer, and includes the first, second, and third elements. The window layer is formed on the active layer. The optical filtering layer includes the first, second, and third elements, and is formed on the window layer to block a portion of light having a wavelength in a predetermined wavelength range.
