Here, a simple, scalable and robust strategy for the synthesis of nano-crystalline aluminium nitride (AlN) is demonstrated using low-energy nitrogen ion implantation. Irradiation of polycrystalline aluminium with 14 keV N<ce:inf loc=\"post\">2</ce:inf><ce:sup loc=\"post\">+</ce:sup> ions at a fluence of 1 × 10<ce:sup loc=\"post\">18</ce:sup> ions cm<ce:sup loc=\"post\">−2</ce:sup> results in the formation of nanoscale surface terraces embedded within an amorphous, non-stoichiometric AlN<ce:inf loc=\"post\">x</ce:inf> layer. Subsequent thermal annealing drives the transformation of this intermediate phase into stoichiometric, nano-crystalline AlN across both near-surface and subsurface regions. Implantation-induced shift in the Fermi level due to implanted immobile atoms lead to a pronounced modulation of the work function, as observed in both amorphous and nano-crystalline (101) aluminium nitride. This structural and electronic evolution is accompanied by a substantial bandgap expansion from 1.63 eV (pristine Al) to 6.2 eV (nano-crystalline with preferential (101) orientation AlN) with a significant modulation refractive index. Further, the emission of yellow photon with comparatively lesser line width (nano-crystalline (101) aluminium nitride) under blue light excitation is observed. Remarkably, the pre-annealed amorphous AlN<ce:inf loc=\"post\">x</ce:inf> nano-terraces exhibit strongly enhanced field-induced electron emission with a lowest turn-on field of 2.1 V µm<ce:sup loc=\"post\">−1</ce:sup>, well described by Fowler–Nordheim quantum tunnelling and supported by local density-of-states analysis. The amorphized phase exhibits superior electron emission characteristics, while the defect-engineered nano-crystalline phase displays yellow photoluminescence with comparatively narrow line width. Collectively, these findings demonstrate that ion-implantation based fabrication of aluminium nitride which enables controlled amorphization and crystallization, yielding distinct functional advantages. This dual-functional tunability establishes ion implantation as a robust and versatile strategy for synthesizing nano-crystalline (101) AlN with tailored optical and electronic properties, positioning it as a promising candidate for next-generation photonic and vacuum based microelectronic devices.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"25 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148402022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, nanoindentation experiments and molecular dynamics simulations with a cube-corner indenter were conducted to investigate the mechanical response and microstructural evolution of the sapphire C-plane under different crystallographic orientations. The results reveal pronounced anisotropy in nanomechanical behavior, with a hardness difference of 1.43 GPa between the hardest and softest orientations. Plastic deformation is controlled by localized amorphization, dislocation slip, and twinning, and the anisotropic response originates from orientation-dependent activation of these mechanisms, supported by Schmid factor analysis. Simulations combined with TEM characterization show that when the angle θ between one indenter edge and the &lt;<mml:math altimg=\"si2.svg\"><mml:mover accent=\"true\"><mml:mrow><mml:mn>1</mml:mn></mml:mrow><mml:mrow><mml:mo stretchy=\"false\">¯</mml:mo></mml:mrow></mml:mover></mml:math>100&gt; direction on the C-plane is 60°, basal slip and R-plane twinning are suppressed, causing localized amorphization to dominate. In addition, trigonal symmetry and ordered aluminum vacancies produce hard and soft prismatic slip directions, further inhibiting slip at θ = 60° and increasing crack initiation probability. To address machining issues caused by anisotropy, high-temperature nanoindentation simulations were conducted. At 900 K, anisotropy and defect formation are markedly reduced, with deformation dominated by basal slip and twinning, while prismatic slip disappears and adhesion weakens significantly.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"139 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148357105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
