We report a method to promote photoluminescence emission in graphene materials by enhancing carrier scattering instead of directly modifying band structure in multilayer reduced graphene oxide (rGO) nanospheres. We intentionally curl graphene layers to form nanospheres by reducing graphene oxide with spherical polymer templates to manipulate the carrier scattering. These nanospheres produce hot...

Heat-carrier heating device is an important part of biomass pyrolysis oil equipment. In particular, the application of vertical heat-carrier heating device can improve the rate of biomass pyrolysis. In this article, we will analyze the vertical carrier heating device based on FLUENT software and model the temperature field and velocity field of hot gas and carrier so as to draw a conclusion tha...

Transport in photoactive graphene heterostructures, originating from the dynamics of photogenerated hot carriers, is governed by the processes of thermionic emission, electron-lattice thermal imbalance, and cooling. These processes give rise to interesting photoresponse effects, in particular negative differential resistance (NDR) arising in the hot-carrier regime. The NDR effect stems from a s...

Strong electron-electron interactions in graphene are expected to result in multiple-excitation generation by the absorption of a single photon. We show that the impact of carrier multiplication on photocurrent response is enhanced by very inefficient electron cooling, resulting in an abundance of hot carriers. The hot-carrier-mediated energy transport dominates the photoresponse and manifests ...

As semiconductor devices enter the deep sub-micron era, reliability has become a major issue and challenge in VLSI design. Among all the failure mechanisms, hot-carrier eeect is one of those which have the most signiicant impact on the long-term reliability of high-density VLSI circuits. In this paper, we address the problem of minimizing hot-carrier eeect during the technology mapping stage of...

This paper aims to outline some of the key challenges towards a HCI for positive change. Drawing on previous empirical studies concerning the development of positive expressive technologies for social wellness, this paper is a delineation of some of the key challenges in terms of theoretical underpinnings, design and evaluation of technologies that aim to contribute to happy beings in

This panel will take the form of a public debate about whether the conference of which it forms part has a future. Academic conferences are increasingly hard to cost-justify and growing awareness of the environmental impact adds to the negative aspects – especially when the HCI community have developed so many tools and techniques to afford virtual collaboration, dissemination and critique. Yet...

Rapid advancements are being made in the field of HCI. However, most commercial designs using these technologies employ limited control schema and privilege interactions borrowed from pre-existing technologies. This paper suggests considering the whole body to create rich environments using coadaptive technologies.
