摘要：

The doping behavior elf carbon doped GaAs materials grown by low pressure MOVPE has been studied. Heavily carbon-doped GaAs layers with hole concentration in the range of 1.5 x 10(19)cm(-3) to 1.9 x 10(20)cm(-3) were obtained. Two different metallization schemes, Ti/Au and Au/Zn/Au, were deposited onto these heavily carbon-doped GaAs layers respectively And the contact resistance before and after alloying was measured using the transmission line method The relation between hole concentration in GaAs layers and Ohmic contact resistance has been obtained. The influence of alloy process on contact resistance has also been studied. The specified contact resistivity lower than 10(-6)Omega.cm has been achieved in GaAs/TiAu no-alloying structures.
