摘要:
Photodetector arrangements, designs and fabrication techniques are described related to semiconductor nanostructures. Arrangements and techniques are described which utilize a nano-patterned template for growing semiconductor nanostructures and/or heterostructures. Resulting photodetectors are also described.
摘要:
A method for forming composite anti-reflective (AR) sol gel-derived coatings includes forming a first chalcogenide compound sol and forming a second chalcogenide compound sol. The first and second sol are mixed to form a mixed sol. The mixed sol is thermally treated at a maximum temperature of no more than 100° C. for (i) drying the mixed sol to form a composite gel and (ii) removing OH− species from the composite gel to form a highly amorphous state AR coating.
摘要:
An infrared transmissive article includes an infrared transmissive substrate and a single layer anti-reflective (AR) composite broadband sol gel coating on a surface of the substrate. The AR coating includes a first chalcogenide including compound, and a second chalcogenide including compound intermixed with the first chalcogenide including compound. The percentages of the first chalcogenide and the second chalcogenide in the AR coating are selected to provide a refractive index of the AR coating that approximates the square root of a refractive index of the substrate.
