  • Abstract
    Effects of side recess on kink effect and transconductance (gm) frequency dispersion characteristics of 0.13μm InGaAs p-HEMTs having InAlAs and InP surface were investigated. The p-HEMT having a 300 nm recessed InP surface showed negligible kink effect and gm dispersion due to the reduction in surface-state induced trap density in the InP etch-stop and impact-ionization induced hole current (Ig,hole).
