Abstract Given the atomic structure data, especially with semiconductors, physicists have been really inter- ested in studying the trapping phenomena observed in them since very early times for reasons well known. One can refer to a lot of literature involving such studies attempting different approaches with the aim of studying their effects on various aspects viz. the electrical properties. Since this data is ought to be large enough in size, it gives us a strong reason to believe in attempting a different approach – of mining patterns – to possibly identify them in the given structure or characterize their existence and its effects. We aim to tap the inherent regularity in these structures and identify the possible divergence from it.
Our aim for undertaking this work has been two-fold. Firstly, as a very initial step, we have attempted to study these atomic structures, starting with Silicon, for their regularities (patterns) and uncover certain parameters which can point out the existence of vacancies leading to slight perturbations in the effective bond-lengths. Secondly, the way this approach is brought to effect is with the help of a generic and parallel pattern mining algorithm – PARAMINER – in turn also analyzing PARAMINER’s genericity and performance. We believe this approach of mining patterns from atomic structure, though implemented for Silicon here, is extendable to others and can yield satisfactory results with minor customizations as need be. In this work, we present our observations and corresponding preliminary results.
