Show affiliationsWe report the synthesis of aligned wurtzite InN nanofingers by the ion-beam assisted filtered cathodic vacuum arc technique. InN nanofingers exhibit a polycrystalline structure. Photoluminescence (PL) and field emission properties of the InN nanofingers were studied. The PL emission peak was centred at ~1.1 eV with a full width at half maximum of 105 meV. The field emission characteristic was observed from the InN nanofingers with turn-on field of 9.7 V µm−1 at a current density of 10 µA cm−2. The formation of InN nanofingers was attributed to the Volmer–Weber growth mode.
