Multilayer MoTe ₂ Field?Effect Transistor at High Temperatures

Electrical stability of multilayer MoS2 fieldeffect transistor under negative bias stress at various temperatures

Life at high temperatures.

Water environments with temperatures up to and above boiling are commonly found in association with geothermal activity. At temperatures above 60 degrees C, only bacteria are found. Bacteria with temperature optima over the range 65 degrees to 105 degrees C have been obtained in pure culture and are the object of many research projects. The upper temperature limit for life in liquid water has n...

Thermal diagnostic of power transistor at increased junction temperatures

Infrared (IR) thermography in power-cycling experiments was combined in reliability studies of an RF power amplifier, operating at elevated junction temperatures. A powercycling technique (adjusted to reach high junction temperatures) was used as a life acceleration method. Several sets of IR measurements were performed for various working conditions to correlate the device power and the maximu...

Nanotribology at high temperatures

Recent molecular dynamics simulation results have increased conceptual understanding of the grazing and the ploughing friction at elevated temperatures, particularly near the substrate's melting point. In this commentary we address a major constraint concerning its experimental verification.

QuantumRatchets at High Temperatures

Using the continued-fraction method we solve the Caldeira-Leggett master equation in the phase-space (Wigner) representation to study Quantum ratchets. Broken spatial symmetry, irreversibility and periodic forcing allows for a net current in these systems. We calculate this current as a function of the force under adiabatic conditions. Starting from the classical limit we make the system quanta...
