Back-end and Flexible Substrate Compatible Analog Ferroelectric Field Effect Transistors for Accurate Online Training in Deep Neural Network Accelerators
Sayani Majumdar, Ioannis Zeimpekis
Online training of deep neural networks (DNN) can be significantly accelerated by performing in-situ vector matrix multiplication in a crossbar array of analog memories. However, t…
Hysteretic magnetoresistance in polymeric diodes
Sayani Majumdar, Himadri S. Majumdar, Harri Aarnio +1
We report on hysteretic organic magnetoresistance (OMAR) in polymeric diodes. We found that magnitude and lineshape of OMAR depends strongly on the scan speed of the magnetic field…
Correlation between Organic Magnetoresistance (OMAR) and Ferromagnetic ordering
Sayani Majumdar, Himadri Majumdar, Jan-Olof Lill +3
We report observation of ferromagnetic (FM) ordering in organic semiconductors, namely regio-regular poly (3-hexyl thiophene) (RRP3HT) and 1-(3-methoxycarbonyl)propyl-1-phenyl-[6,6…
Towards printed magnetic sensors based on organic diodes
Sayani Majumdar, Himadri S. Majumdar, Daniel Tobjork +1
We report the study of magnetotransport properties of regio-regular poly (3-hexyl thiophene) based organic diodes. The devices were fabricated using two different techniques of spi…
The role of electron-hole recombination in organic magnetoresistance
Sayani Majumdar, Himadri S Majumdar, Harri Aarnio +3
Magneto-electrical measurements were performed on diodes and bulk heterojunction solar cells (BHSCs) to clarify the role of formation of coulombically bound electron-hole (e-h) pai…
A room-temperature polymeric spin-valve
Sayani Majumdar, Himadri S. Majumdar, Reino Laiho +1
We report giant magnetoresistance up to 150 percent at low bias current and low temperature as well as room temperature magnetoresistance in polymeric spin-valves having the struct…
