摘要：

Compared　with　the　nonalloyed　AuGeNi/Au-based　ohmic　contacts　to　n-GaAs　in　convention,　the　nonalloyed　Cr/Au　is　a　non-magnetic　material　which　has　low　ohmic　contact　resistivity　and　it　eliminates　the　effect　of　the　laser　as　a　light　source　on　the　sensitivity　of　the　magnetic　measuring　equipment.　In　this　paper,　the　n-GaAs　ohmic　contact　resistivity　of　VCSEL　based　on　non-magnetic　materials　Cr/Au　is　measured　by　circular　dot　transmission　line　model　(CDTLM),　and　VCSEL＇s　reliability　is　studied　by　conductance　curve　method.　©　2018　IEEE.
