概要 In this letter, we have reported a lateral diamond Schottky barrier diode (SBD) that was fabri- cated on a heteroepitaxial diamond substrate using all ion-implantation processes. The SBD exhibited a lower reverse leakage current, which resulted in an unprecedent- edly high rectification ratio of 3.6 × 105 when compared to ion-implanted diamond diodes. The reverse breakdown voltage was measured to be 1.65 kV- the highest measure- ment ever reported among ion-implanted diamond devices. In addition, the ideality factor and Schottky barrier height were determined as 4.9 and 1.4 eV, respectively, under the forward bias conditions. This study revealed the improve- ment of ion-implanted diamond SBD by using high-quality heteroepitaxial diamond substrates and low channel doping concentration.
