UNOGAN

Unveiling down to 0-dimensional confinements in GaN devices for RF power application

Grant period	2020-10-10 - 2022-10-09
Funding body	European Union
Call number	H2020-MSCA-IF-2019
Grant number	896390
Identifier	G:(EU-Grant)896390

Note: UNOGAN aims at developing a fundamental approach for quantitative assessment of polarization-induced 2D carriers (and their type) or junctions at the interface(s) and focuses on unraveling chemical and electronic properties of critical regions, for e.g., recessed surfaces of the gate, which is expected to shed a deeper insight into one of the severe challenges GaN industry is facing. Though successfully applied in narrow-bandgap semiconductors like Si, this SPM based approach currently face challenges of highly resistive wide band gap (Al,Ga)N. In the project, not only identification of the key issues but major improvements and even key instrumental development of E-SPM is proposed for such a rigid system, from which a correlated-analysis of spatially resolved local potential, charge and resistance in combination with computational methodology could be developed. This approach will lead to major advancements in the improvement of III-nitride based high electron mobility transistors (HEMTs) program of IMEC. Over the years, the applicant has gained significant experience in the electrical study of III-nitride materials through scanning probe, defect sensitive spectroscopies and transmission electron microscopies. UNOGAN research will channel this knowledge towards new horizons at the forefront of materials science, building a strong collaboration network involving well-established European laboratories and companies which are leaders in the field. The new skills acquired during the two-year project will serve him to boost his research career, gain independence and place the host institution as an international reference in nanoscale device characterization.
