An energy‐momentum transport model for sub‐micron silicon devices is modified to include new sets of simple interband scattering models representing impact ionization, auger recombination, trapping and photo generation. These have been developed using a simplified physical modelling approach. A discretization scheme suitable for application to an irregular spatial grid is presented. The resulting model is suitable for the study of small geometry effects in silicon devices.

Despite increased academic research interest on how media sources represent and impact social realities, there is little emphasis on homelessness representations in street newspapers. The Greek economic crisis echoed socioeconomic changes and inequalities in both mainstream and lesser-known media with various framing representations of homelessness. One Greek journalistic effort born midcrisis was the street paper ‘Schedia’, which merits examining for its popularity and success as a component of the social reintegration program that launched it. Through the lens of our case study on Schedia and drawing mostly on contemporary interdisciplinary approaches from Cultural Studies and Media Communication, we provide a brief literature review on ‘homelessness street journalism’ research and explore theoretical interpretations thereof. We then discuss media discourse and framing of homelessness and whether it reveals utilisation of street journals mainly as tools for raising awareness or for creating income to maintain or augment social reintegration efforts and programs. We content analysed one year of Schedia's issues and examined instances of both perceived and experienced homelessness representations and causes therein, offering a snapshot of the ways and extent to which Schedia represents homeless voices. Lastly, through the example of Schedia, we discuss whether street media lends itself best as a voice for democratic empowerment of the homeless or as an identity-building intermediary tool for capacitating transformative social reintegration.
