Ballistic thermoelectric transport in structured nanowires

open access: yesNew Journal of Physics, 2014
Thermoelectric (TE) devices are solid-state energy converters that can be used for power generation through the Seebeck effect and TE cooling through the Peltier effect. Nanostructures give great opportunities to engineer TE energy conversion efficiency.

Ballistic spin resonance [PDF]

open access: yesNature, 2009
The phenomenon of spin resonance has had far reaching influence since its discovery nearly 70 years ago. Electron spin resonance (ESR) driven by high frequency magnetic fields has informed our understanding of quantum mechanics, and finds application in fields as diverse as medicine and quantum information.

Sprinting Speed Increases Through Postactivation Performance Enhancement with a Hex-Bar Farmers Walk [PDF]

open access: yesJournal of Kinesiology and Exercise Sciences
Background: An acute increase in maximum strength, power, or speed following a conditioning contraction, known as a postactivation performance enhancement (PAPE), has been previously determined to be better performed when the initial exercise is of the ...

Numerical Analysis of Diameter Dependency of Control Coefficient of Carbon Nanotube Field Effect Transistor

open access: yesMajlesi Journal of Electrical Engineering
This study examines the behavior of carbon nanotube field effect transistors under ballistic conditions by analyzing the effect of gate (α_G) and drain (α_D) control coefficient modifications on the device's diameter. The effect of α_G and α_D on the

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...
