Title:StudyontheRelationshipbetweenPerformanceofInGaAsDetectorsandSurfaceAreaandPerimeter
Abstract:
InGaAs(IndiumGalliumArsenide)detectorshavegainedsignificantattentioninthefieldofoptoelectronicsduetotheirexcellentperformanceinnear-infraredwavelengthrange.ThisstudyaimstoinvestigatetherelationshipbetweentheperformanceofInGaAsdetectorsandtheirsurfaceareaandperimeter.ByvaryingthesurfaceareaandperimeterofInGaAsdetectorsandanalyzingtheirperformance,valuableinsightsintothedesignandoptimizationofInGaAsdetectorscanbeobtained.
Introduction:
InGaAsdetectorsarewidelyusedinvariousapplicationssuchastelecommunications,spectroscopy,andnightvisionduetotheirhighsensitivityandrapidresponseinthenear-infrared(NIR)range.TheperformanceofInGaAsdetectors,includingresponsivity,darkcurrent,andquantumefficiency,iscrucialfortheirsuccessfulapplicationinthesefields.However,theunderstandingoftherelationshipbetweenthedetector'ssurfaceareaandperimeteranditsperformanceisstilllimited.ThisstudyaimstofillthisknowledgegapandcontributetotheoptimizationofInGaAsdetectors.
