  • Abstract
    We have fabricated InP Gunn diodes with two different wet chemical etchants for MESA etching and compared the results. In order to make a comparative study, we have used two wet chemical etchants; one was HCl-based etchant (HCl : H3PO4 : H2O = 3:1:2), the other one was FeCl3 light sensitive etchant. It was shown that the fabricated diodes have the currents of 201 and 250 mA, and the breakdown voltage of below 8 V and over 11 V, respectively.
