We reconsider the semiconductor trions from scratch. We first
determine the very many “reasonable” ways to write the trions in
first quantization. We then select the forms which are easy to
relate to physical pictures. In a second part, we derive the
corresponding creation operators in second quantization. We pay
particular attention to the expression of the 
trion in
terms of exciton and free-electron, as it is the one adapted to
future works on many-body effects with trions.
