Background:

• Traditional silicon (Si) functionalization relies on indirect dopant attachment via O-Si or C-Si bonds.
• Direct B-Si bonds offer superior electronic properties, positioning Si as a next-generation electronic material.
• Solvothermal methods are sought for scalable synthesis of direct dopant-Si bonds.

Purpose of the Study:

• To investigate the reactivity of dichlorophenylborane with H-Si(100) under solvothermal conditions.
• To explore a novel solvothermal route for forming direct boron-silicon (B-Si) bonds.
• To assess the potential of this method for next-generation electronic materials.

Main Methods:

• Experimental investigation of dichlorophenylborane reaction with H-Si(100).
• Computational studies to analyze reaction pathways and product formation.
• Characterization of B-Si bond formation using solvothermal synthesis.

Main Results:

• Dichlorophenylborane reacts with H-Si(100) to form direct B-Si bonds.
• The phenyl group remains attached to boron, preventing competitive Si-C bond formation.
• A new solvothermal method for direct B-Si bond synthesis was established.

Conclusions:

• The phenyl-substituted boron precursor facilitates direct B-Si bond formation via a novel solvothermal route.
• This method avoids undesired Si-C bond formation, crucial for achieving desired electronic properties.
