Claim 0:
1. A method for forming an Indium-containing film, the method comprising the steps of:
exposing a substrate to a vapor of a film forming composition; wherein the film forming composition comprises a heteroalkylcyclopentadienyl Indium (I) precursor having a general formula:

In[R1R2R3R4CpL1] or

In[CpL1L2y], wherein Cp represents a cyclopentadienyl ligand; R1 to R4 are each independently H, C1-C4 linear, branched or cyclic alkyls; L1 and L2 are each independently a substituent bonded to the Cp ligand and consisting of an alkyl chain containing at least one heteroatom selected from Si, Ge, Sn, N, P, B, Al, Ga, In, O, S, Se, Te, F, Cl, Br, I; and y=1-4; and
depositing at least part of the heteroalkylcyclopentadienyl Indium(I) precursor onto the substrate to form the Indium-containing film using a vapor deposition method.
