The core principle of a research paper is to extend knowledge in a very specific field. Basically a paper reviews what has been done, is known to date; then a description of your contribution; and a comparison / evaluation wrt to what is already accepted knowledge / practice. Research papers published in peer-reviewed journals are rarely written by one individual. There generally are collaborators, principal investigators. i.e. co-authors. However, unpublished research papers might be written as part of some course requirement, especially as part of a capstone project. From your question it is unclear as to what level you are contemplating.
