Multiscale Green's functions for modeling graphene and other Xenes

January 27, 2023
Author(s)
Vinod Tewary, Edward Garboczi
We give a review of the multiscale Green's function method for modeling modern two-dimensional nanomaterials such as graphene and other Xenes. The method is applicable to materials at different space and time scales and is computationally efficient. This

High-Resolution DNA Hybridization Kinetics Measurements with Double Gate FD-SOI Transistors

January 23, 2023
Author(s)
Seulki Cho, Alexander Zaslavsky, Curt A. Richter, Jacob Majikes, James Alexander Liddle, Francois Andrieu, Sylvain Barraud, Arvind Balijepalli
Double gate fully depleted SOI transistors operating in a remote gate configuration and under closed-loop feedback allow noise performance that exceeds their single gate counterparts by more than an order of magnitude. We leverage this high performance to

On the "intrinsic" breakdown of thick gate oxide

October 12, 2022
Author(s)
Kin (Charles) Cheung
Thick gate oxide breakdown mechanism becomes an important topic again due to the rising demand of power electronics. The failure of the percolation model in explaining the observed Weibull shape factor of thick oxide breakdown distribution seriously

Towards the Physical Reliability of 3D-Integrated Systems: Broadband Dielectric Spectroscopic (BDS) Studies of Material Evolution and Reliability in Integrated Systems

September 30, 2022
Author(s)
Papa Amoah, Joseph J. Kopanski, Yaw S. Obeng, Christopher Sunday, Chukwudi Okoro, Lin You, Dmirty Veksler
In this paper, we present an overview of our current research focus in developing non-destructive metrology for monitoring reliability issues in 3D-integrated electronic systems. We introduce a suite of non-destructive metrologies that can serve as early

Degradation of CVD-Grown MoS2 Subjected to DC Electrical Stress

September 16, 2022

Semiconductors are critical to our Nation's economic growth, national security, and public health and safety. Revolutionary advances in microelectronics continue to drive innovations in communications, information technology, health care, military systems

How to Report and Benchmark Emerging Field-Effect Transistors

July 29, 2022
Author(s)
Zhihui Cheng, Chin-Sheng Pan, Peiqi Wang, Yanqing Wu, Davood Shahrjerdi, Iuliana Radu, Max Lemme, Lian-Mao Peng, Xiangfeng Duan, Zhihong Chen, Joerg Appenzeller, Steven Koester, Eric Pop, Aaron Franklin, Curt A. Richter
Emerging low-dimensional nanomaterials have been studied for decades in device applications as field-effect transistors (FETs). However, properly reporting and comparing device performance has been challenging due to the involvement and interlinking of

Determination of Domain Wall Velocity and Nucleation Time by Switching Dynamics Studies of Ferroelectric Hafnium Zirconium Oxide

July 22, 2022
Author(s)
Xiao Lyu, Pragya Shrestha, Mengwei Si, Panni Wang, Junkang Li, Kin (Charles) Cheung, Yu Shimeng, Peide Ye
In this work, we present the first experimental determination of nucleation time and domain wall (DW) velocity by studying switching dynamics of ferroelectric (FE) hafnium zirconium oxide (HZO). Experimental data and simulation results were used to
