Ion channeling is widely used to study the defect densities and their location in crystalline materials; it also allows determination of the strain in epitaxial layered structures. A detailed knowledge of inter-atomic potentials for such channeled particles is needed for proper understanding and interpretation of various observations in the field of channeling. A model for the description of long-range electron-ion interactions affecting the potentials due to heavy impurities see by external probe particles in otherwise perfect crystals can be derived. The resulting formulation will envisage the modifications in the screening functions. Utilization of the ion channeling for characterizing synthetically modulated structures like semiconductor superlattices is another area of special interest. Strained Layer Superlattices (SLS) have unique electronic and opto-electronic properties and find wide ranging applications in many frontier areas of science and technology. These are layered structures of alternating composition of materials having lattice mismatch (~0.1% to 2.0%) which is accommodated by biaxial (compressive or tensile) strains in the plane of the layers; each layer acquires a perpendicular lattice constant due to strain accommodation. Beyond a critical thickness, the strain in the layers relaxes giving rise to misfit dislocations. The presence of defects deteriorates the performance of these devices and thus it is important to characterize strain and strain-relief mechanisms and also the limits of strained-layer growth in the structures. My thesis work is an effort to address these two problems and hence is divided into two parts; (i) theoretical work on the interatomic potential for a positively charged particle channeled in a crystal with point defects and (ii) characterization of Strained-Layer Superlattices by Ion Channeling in comparison with other characterization techniques like XRD and Raman Spectroscopy. Samples for this experimental work are grown using the OMVPE facility at Tata Institute of Fundamental Research (TIFR), Mumbai, and studied at the Institute of Physics (IoP), Bhubaneswar, Indian Institute of Technology (IIT), Kanpur, Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam and Alabama A & M University, Alabama, USA.

An ion beam of a given fluence can cause intermixing of atomic layers at the interface, a phenomenon called Ion Beam Mixing which has long been recognized as an alternative to high dose ion implantation in various metal-insulator, metal-metal and metal-semiconductor alloys. Ion beam mixing can cause structural changes at the interface in SLS, resulting in a change in the band gap. With a controlled dosage band gap engineering or band gap tuning of the SLS can be achieved. Swift Heavy Ion beam induced mixing is more suitable for the integration of optoelectronic devices because of the advantage that interface mixing can be confined to a narrow region at the interface as against the lateral straggling effects in low energy ion irradiation.

We have carried out high-energy ion irradiation on SLS and characterized the samples by and ion channeling and high resolution XRD for the strain measurements before and after the irradiation. The basic thrust of this work viz. the growth, characterization and band gap tuning of SLS, is to utilize the advantages of unusual transport, optical and opto-electronic properties.

An important class of organic polymeric materials is electrically conducting polymers also known as organic semiconductors, which have many applications in optical, electronic and optoelectronic and sensory devices. Polyaniline is the most studied polymer of this class. Dramatic modifications have been observed in Swift Heavy Ion irradiated polymers as a result of large energy deposition to the polymer. These changes in the macro-properties like structural, electrical, optical and thermal properties can be traced to transformations at the micro-level through cross-linking, chain scissoring, bond breaking and cluster formation due to the energy deposited by SHI beam. We have also taken up a systematic study of synthesis, characterization and SHI Irradiation of Conjugated Polymers in a research project (UFUP 37302 sponsored by Inter University Accelerator Centre, New Delhi).
