  • Patent number: 11925451
    Abstract: The present disclosure discloses a method for synthesizing high-quality magnetic resonance images, wherein the method expands the value ranges of echo time TE and repetition time TR in a magnetic resonance signal formula to negative intervals, and expands the contribution of proton density PD to a negative power. The method can effectively reduce the influence of the measurement error of quantitative magnetic resonance imaging tissue parameters on the tissue contrast of the synthetic magnetic resonance image, and can obviously improve the tissue contrast of the synthetic magnetic resonance image. This method will significantly improve the imaging quality of synthetic magnetic resonance imaging, and promote its detection effect in neuroscience and clinical lesions. This method is expected to improve the imaging quality of synthetic magnetic resonance imaging and promote its detection effect in neuroscience and clinical lesions.

  • Publication number: 20230307579
    Abstract: A method to fabricate micro-size III-nitride light emitting diodes (?LEDs) with an epitaxial tunnel junction comprised of a p+GaN layer, an InxAlyGazN insertion layer, and an n+GaN layer, grown using metalorganic chemical vapor deposition (MOCVD), wherein the ?LEDs have a low forward the GaN layers, which reduces a depletion width of the tunnel junction and increases the tunneling probability. The ?LEDs are fabricated with dimensions that vary from 25 to 10,000 ?m2. It was found that the InxAlyGazN insertion layer can reduce the forward voltage at 20 A/cm2 by at least 0.6 V. The tunnel junction ?LEDs with an n-type and p-type InxAlyGazN insertion layer had a low forward voltage at 20 A/cm2 that was very stable. At dimensions smaller than 1600 ?m2, the low forward voltage is less than 3.2 V.

  • Publication number: 20230005793
    Abstract: A method of removing a substrate from III-nitride based semiconductor layers with a cleaving technique. A growth restrict mask is formed on or above a substrate, and one or more III-nitride based semiconductor layers are grown on or above the substrate using the growth restrict mask. The III-nitride based semiconductor layers are bonded to a support substrate or film, and the III-nitride based semiconductor layers are removed from the substrate using a cleaving technique on a surface of the substrate. Stress may be applied to the III-nitride based semiconductor layers, due to differences in thermal expansion between the III-nitride substrate and the support substrate or film bonded to the III-nitride based semiconductor layers, before the III-nitride based semiconductor layers are removed from the substrate. Once removed, the substrate can be recycled, resulting in cost savings for device fabrication.

A device is processed for each of the island-like semiconductor layers. Etching is performed until at least a part of the growth restrict mask is exposed. The devices are then bonded to a support substrate. The GaN-based substrate is removed from the devices by a wet etching technique that at least partially dissolves the growth restrict mask. The GaN substrate that is removed then can be recycled.
