Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

On the Design of Micro-Mobility Scheme for Mobile Networks

open access: yes, 2007
由90年代以降,隨著製造技術與材料科學的進步,越來越多的行動裝置進入了每個人的日常生活,而另一方面,網際網路的成長使人類的生活及相互溝通更無遠弗屆。此時,因為無線通訊技術的發展,使兩者結合在一起,造就了隨時與隨地,使用者都可以運用手邊的行動裝置來存取網路的現象。但以目前的發展看來,絕大部份的應用及通訊協定的限制,都使得這些行動裝置僅具有可攜性(Portable),尚不具備移動性(Mobility),不過這絕對是未來的發展方向。為此,學界也早在90年代就以發展出行動IP(Mobile IP)的技術 ...

Neuromorphic Electronics for Intelligence Everywhere: Emerging Devices, Flexible Platforms, and Scalable System Architectures

open access: yesAdvanced Materials, EarlyView.
The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...

A SURVEY ON MICRO MOBILITY MANAGEMENT OF HOST IDENTITY PROTOCOL

open access: yesElectrica, 2011
Host Identity Protocol (HIP) is a new protocol that employs the idea of separation of the role of IP addresses as host identification and location identifier. It also introduces protocol level security in its nature.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

open access: yesAdvanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Agent-based simulation model of micro-mobility trips in heterogeneous and perceived unsafe road environments

open access: yesJournal of Cycling and Micromobility Research
Safety concerns expressed by micro-mobility users seem to practically constrain the use and flexibility of these new modes. This paper introduces a new, parametric agent-based modeling approach for simulating micro-mobility, using MATSim as a platform ...
