  We report enhanced two-component superconductivity in (CoSi2/Si)/TiSi2
superconductor/normal-metal (S/N) heterojunctions. An enhanced superconducting
transition temperature about twice that of CoSi2 and an upper critical field
about 20 times bigger than that of epitaxial CoSi2/Si films were found. The
tunneling spectra of three-terminal S/N junctions show pronounced zero-bias
conductance peaks (ZBCPs) that signify penetration of odd-frequency,
spin-triplet and even-parity Cooper pairs in TiSi2 from triplet dominant
pairing in CoSi2/Si driven by symmetry reduction at the CoSi2/Si interface.
Both the enhancement of the superconducting transition temperature and the
ZBCPs are found to be more pronounced if TiSi2 is made more diffusive.
