Journal ArticleDOI
Light-emitting diodes enhanced by localized surface plasmon resonance
TL;DR: The prospect, including the potential to replace fluorescent/incandescent lighting devices as well as applications to flat panel displays and optoelectronics, and future challenges with regard to the design of metallic nanostructures and fabrication techniques are discussed.
Journal ArticleDOI
Extremely confined terahertz surface plasmon-polaritons in graphene-metal structures
TL;DR: In this article, a deep subwavelength terahertz plasmonic waveguide based on a graphene-metal hybrid structure is proposed, and a broadband mode confinement down to 1/100 of the free-space wavelength λ 0 with a loss of 0.6 dB/λ 0 is achieved when the intra-band electron relaxation time is 100 ps.
Journal ArticleDOI
Unsupervised Learning Using Charge-Trap Transistors
Xuefeng Gu,Subramanian S. Iyer +1 more
TL;DR: Experimental data from 22-nm silicon-on-insulator devices reveal that a charge-trap transistor possesses promising characteristics for implementing synapses in neural networks, such as very fine tunability, weight-dependent plasticity, and low power consumption.
Journal ArticleDOI
An Analog Neural Network Computing Engine Using CMOS-Compatible Charge-Trap-Transistor (CTT)
Yuan Du,Li Du,Xuefeng Gu,Jieqiong Du,X. Shawn Wang,Boyu Hu,Jiang Ming-Zhe,Xiaoliang Chen,Subramanian S. Iyer,Mau-Chung Frank Chang +9 more
TL;DR: An analog neural network computing engine based on CMOS-compatible charge-trap transistor (CTT) is proposed and obtained a performance comparable to state-of-the-art fully connected neural networks using 8-bit fixed-point resolution.
Journal ArticleDOI
Charge-Trap Transistors for CMOS-Only Analog Memory
TL;DR: A comprehensive investigation of the programming behavior of CTTs, including analog retention, intra- and inter-device variation, and fine-tuning of the device, both for individual devices and for devices in an integrated array reveals the promising future of using the CTT as a CMOS-only analog memory device.
