Abstract :
We present the results of a study on epitaxial transfer of InP-based heterostructure barrier varactor (HBV) materials onto a silicon substrate employing the low-temperature plasma-activated bonding technique. The test diodes fabricated on the bonded samples exhibit symmetric electrical characteristics, over the temperature range of 25°C-165°C, and show no degradation compared to previously reported InP-based diodes. Moreover, the onset temperature for debonding, the effective barrier height extracted from the measured data, and the maximum voltage of the HBVs for a current density of 100 A/cm2 were extracted to be 260°C, 0.56 eV, and 10.5 V, respectively.
