High-Field Breakdown and Thermal Characterization of Indium Tin Oxide Transistors

Haotian Su, Yuan-Mau Lee, Tara Peña, Sydney Fultz-Waters et autres

Amorphous oxide semiconductors are gaining interest for logic and memory transistors compatible with low-temperature fabrication. However, their low thermal conductivity and heterogeneous interfaces suggest that their performance may be severely limited by self-heating, especially at higher power and device densities. Here, we …

Introduction to Carbon Sensing in Soil. A surface-level review of traditional and alternative methods of soil carbon measurement

Sydney Fultz-Waters

Soil carbon can be divided into two categories: organic and inorganic. Soil inorganic carbon (SIC) is present in carbonate minerals in the soil and is often found in dry, arid regions. Examples of SIC include calcium carbonate (CaCO3) and magnesium carbonate (MgCO3), …
