Hot carrier extraction occurs in 2D semiconductor photoelectrochemical cells [Austin et. al., PNAS, 2023, 120, e2220333120]. Boosting the energy efficiency of hot carrier-based requires maximizing carrier...

We present a microscopic study on the impact of doping on the carrier dynamics in graphene, in particular focusing on its influence on the technologically relevant carrier multiplication in realistic, doped graphene samples. Treating the time- and momentum-resolved carrier-light, carrier-carrier, and carrier-phonon interactions on the same microscopic footing, the appearance of Auger-induced ca...

This topic introduces the concept of Hot Swapping DC power buses and why hotswapping has become a mainstream requirement, particularly in the telecommunications industry. Several methods of implementing hot swap will be provided along with the pros and cons of each method. Finally, a hot swap design utilizing a Hot Swap Power Manager will be presented for a typical -48V telecom

Over recent years, the study of games and players has become an established domain with HCI research. However, while a range of methods has been employed within this area, questions remain as to how to develop in-depth understandings of players and the contexts they play within. Drawing upon the social sciences, this paper proposes case studies as an additional methodology for player research. ...

In this introductory chapter, we describe the key lessons from an earlier HCI Educators’ conference, held in Limerick in 2006, the outcomes of which led to the theme of HCIEd 2007 – Creativity: Experiencing to Educate and Design. The paper discusses the lessons leant around four key questions: nature vs. nurture: can creative invention be taught; what tools and methods are there to help student...

Gamification has been widely accepted in the HCI community in the last few years. However, the current debate is focused on its short-term consequences, such as effectiveness and usefulness, while its side-effects, long-term criticalities and systemic impacts are rarely raised. This workshop explores the gamification design space from a critical perspective, by using design fictions to help res...

Papers in HCI play different roles, whether to inspire, solve industrial problems or further the science of HCI. There is a potential conflict between the different views, and a danger that different forms of validity are assumed by author and reader — deliberately or accidentally. This paper reviews some of the issues in this complex area and makes
