Abstract: The present disclosure provides a porous bulk material and an electronic apparatus thereof, and an apparatus capable of reducing wind noise and an application thereof. The apparatus comprises an external sound channel, a zeolite material, and a sound pickup hole, wherein the zeolite material is disposed between the external sound channel and the sound pickup hole. The present disclosure further provides an application of the apparatus in an electronic device provided with a microphone. According to the apparatus, the wind noise can be effectively reduced, and the call quality of a communication device is obviously improved.

Abstract: A method for manufacturing an ultraviolet photodetector based on Ga2O3 material are provided. The method includes: selecting a substrate; forming a Ga2O3 layer on an upper surface of the substrate; forming a top electrode on the Ga2O3 layer; and forming a bottom electrode on a lower surface of the substrate. Ga2O3 material is adopted, with a light transmittance in the solar blind area can reach 80% or even 90%. The Ga2O3 material is suitable for application to a light absorbing layer, and its transparent conductive electrical properties are also beneficial to improve the light absorption capacity of the light absorbing layer, thereby greatly improving the device performance of the photodetector diode.
