Analytic Model forAmorphous GST OTS in Phase Change Memory Cell with Hopping Transport

Wang C., Wang H., Wang W., Wang C., Wang H., Wang W., Cao Y., Wang C., Wang H., Wang W., Ye Y., He J., PKU-HKUST Shenzhen-Hongkong Institution, CN

This paper presents an analytic model for amorphous GST OTS in phase-change-memory cell with the hopping transport mechanism, which is widely used in the organic semiconductor device simulation. In this work an equivalent hopping probability [...]

Leakage current in HfO2 stacks: from physical to compact modeling

Larcher L., Padovani A., Pavan P., Università di Modena e Reggio Emilia, IT

First, we present a Monte-Carlo model we developed for describing the charge transport in hafnium-based stacks, which allows reproducing voltage and temperature dependencies of the leakage current along with its statistical distribution. The model accounts [...]

Construction and Electrical Characterization of 0.9 nm Tall Channels Made via Pyryl Phosphonic Acid (PYPA) Self-assembly

Dong J., Parviz B.A., Yip H.L., Ma H., Jen A.K-Y., University of Washington, US

Molecular self-assembly can yield well-defined systems for charge carrier transport for the construction of a variety of devices such as field effect transistors and biosensors. We report a simple method to create an extremely confined [...]
