Aluminum nitride nanocolumns as scatterers were introduced on top of the hBN layer. A lower threshold of 1.38 mJ/cm2 was achieved in samples containing hBN. Significantly higher threshold was observed when no hBN was present. Results suggest the potential of utilising hBN as an ultrathin flexible substrate for random lasing applications.Funding from Ministry of Education - Higher Education (MOE) Malaysia for SLAB Scholarship under Post-Doctoral program is greatly acknowledged.
