Abstract The failure mechanisms caused by electrostatic discharge (ESD) effects at ambient temperatures ranging from −75 to 125°C are investigated by Silvaco TCAD simulator. The devices are NMOS transistors fabricated with 28 nm fully depleted sil

Characterizing the chemistry of complex organic molecules (COMs) at the epoch of planet formation provides insights into the chemical evolution of the interstellar medium (ISM) and the origin of organic materials in our solar system. We report a dete

Ionization drives important chemical and dynamical processes within protoplanetary disks, including the formation of organics and water in the cold midplane and the transportation of material via accretion and magnetohydrodynamic flows. Understanding

H _2 CO is a small organic molecule widely detected in protoplanetary disks. As a precursor to grain-surface formation of CH _3 OH, H _2 CO is considered an important precursor of O-bearing organic molecules that are locked in ices. Still, since gas-

Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to derive disk properties accurately, we need a thorough understanding of the behavior of the molecular probes upon which we rely.

We present MIRI Medium-resolution Spectrograph observations of the large, multi-gapped protoplanetary disk around the T Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9–25.5 μ m toward the inner ∼1 au in the disk
