AB  - Synthesis of omega-alkenyl-terminated silver nanoparticles (AgNPs) and then their 
      immobilization on a hydrogen-terminated silicon surface in two-dimensional 
      arrangement through covalent interaction are demonstrated. The thermal-induced 
      hydrosilylation at mild conditions facilitate nanoparticles assembly through 
      interaction between terminal alkenyl (CH(2)=CH-) groups of AgNPs and 
      hydrogen-terminated silicon surface. The assembly of AgNPs on a silicon surface 
      is characterized by FESEM and XPS. Adequate coating of 10-undecene-1-thiol (UDT) 
      on AgNPs and mild temperature hydrosilylation impede the fusion or aggregation of 
      nanoparticles, while they immobilized on a silicon surface, which is very crucial 
      to preserve the discrete entities of nanoparticles. This elegant and facile 
      approach provides stable monolayer of AgNPs with very good coverage area and 
      promises potential to fabricate electronic devices and solar cells, where 
      nanoparticles needs to be directly attached to the silicon surface without an 
      interfacial oxide thin film.
