一. 报告题目：Planar-processed polymer transistor and its implication to transport exploration（徐勇博士）

内容摘要：

Conjugated polymers came to an unprecedented epoch that the charge transport is limited only by small disorder within aggregated domains. Accurate evaluation of transport performance is thus vital to optimizing further molecule design. Yet the conventional transistors routinely used cannot fulfil such a requirement. Here we show that the extrinsic effects of Schottky barrier, access transport through semiconductor bulk, and concurrent ambipolar conduction seriously influence device characteristics and, in turn, transport analysis. By contrast, planar transistors made by a process similar to that for classical Si MOSFETs exhibit unparalleled performance, with a record subthreshold swing of 85 mV/dec which is approaching the theoretical diffusion limit of 60 mV/dec at room temperature. Their ideal device characteristics enable us to illuminate the ambiguous operating principle of ambipolar transistors in which both of holes and electrons present simultaneously. More importantly, these planar transistors incorporating ohmic contacts and free of access transport and ambipolar conduction provide a great access to exploring the intrinsic charge transport in the promising donor-acceptor (D-A) copolymer semiconductors. It turns out that only those operating in low-field regime are reliable to reveal the intrinsic transport owing to energetic disorder lowering by lateral field.

二. 报告题目：Laser induce electron emission and resistive switching random access memory（朱映彬博士）

内容摘要：

In this talk, I will present our recent works about ultrafast laser induce electron emission from nanostructure and metal-oxide RRAM. We first study the pulse shape effect on electron emission by solving the time dependent Schrödinger equation. Carrier envelope phase effect in the multi-photon regime and tunneling regime is analyzed. Fano resonance induce two color pulse and its application in ultrafast electron emission is investigated. I will also discuss the application of Transformation Optics in strong field physics. Later I develop a single electron model to study the space charge effect in vacuum diode, Coulomb blockage effect and THz frequencies transport behavior are found. A multidimensional model is used to study the space charge effect on electron emission from a tip. We conclude several novel scaling for the study of SCL current. For the second part, I will present our experiment result about electron injection into two layer structure. Improvement on memory effect compared with one layer structure is observed. A bifunctional device simultaneously exhibit light emitting and RS behavior with proper operation will be demonstrated using InGaN/GaN. Lastly, I will show our fabrication of Ga-doped ZnO transparent RRAM.

三. 报告题目：DSP algorithm acceleration on GPUs（邱天博士）

内容摘要：

Digital signal processing (DSP) is one of the most powerful modern technologies, and is one of the main branches of circuits and systems. For over thirty years, we have been using DSP microprocessors to speed up DSP algorithms, which can be 2-6 times faster than those running on contemporary CPUs.

In recent years, massively parallel computing GPU has become a popular tool. The activities of major chip manufacturers such as AMD and NVIDIA make it more evidentthat GPU can be used for general purpose algorithm acceleration. Casesshow that GPUs have outpaced standard CPUs in floating-point performance. Compared with FPGA implementation or VLSI implementation,GPU implementation of DSP algorithms saves a lot of man-power in developing our systems.

In this report, a brief introduction of current status of general purpose GPU is presented first, followed by our implementation example of using a GPU to accelerate the solver of linear algebra problems in our project. After the same algorithm is ported to the GPU platform, our experiment result shows the algorithm can be over 50 times faster than the speed of the algorithm running on a CPU platform.

四. 报告题目：Applications of Printed Electronics on Paper-based Substrates（李庭杰博士）

内容摘要：

Printed electronics (PE) is being increasingly explored for many applications such as OPV, OLED lighting/display, energy storage devices, RFID, etc., and a few of them have even been commercialized. However, the commercial utilization of the PE technologies is mainly on conventional electronic substrates (silicon/glass wafers) and a small portion is on high-quality coated plastics/paper. With an increasing demand for sustainability, PE is attracting interests in packaging (use paper/board-based materials) and also as a tool to market/sell more products by being interactive (touch sensing) and to monitor the movement of packaging and the quality of packaged goods (RFID type of biosensors). Although paper-based packaging is well positioned to meet the requirement of sustainability, applying PE technologies directly onto paper substrates to render the smart functionalities for the packages faces some technical challenges.

This presentation will cover the following topics:

1. The potential opportunities for printing electronics on paper-based substrates for creating sustainable and functional packaging as identified through market analysis and value proposition assessment.

2. How to overcome some technical challenges for printing electronics on paper substrates such as high roughness, non-uniformity of surfaces, low vapor and oxygen barrier, etc.

3. An overview of a few promising concepts based on paper and board that are being explored, including the projects running at FPInnovations and its university partners. These examples will be used to show how to create sustainable and functional paper-based packaging with PE technologies.
