Shot Noise Enhancement in Resonant Tunneling Structures in a Magnetic Field

, 1998
We have observed that the shot noise of tunnel current, I, in GaSb-AlSb-InAs-AlSb-GaSb double-barrier structure under a magnetic field can exceed 2qI. The measurements were done at T=4K in fields up to 5T parallel to the current.

Transcranial Direct Current Stimulation Neuromodulation in Elderly Individuals and Its Impact on Anxiety and Depression Symptoms

AGING MEDICINE, Volume 8, Issue 6, Page 511-522, December 2025.
Anodal tDCS over the left prefrontal cortex, combined with cognitive training, enhanced cognition, reduced anxiety and depression, and improved motor response in elderly women. These findings support tDCS as a safe, effective strategy for promoting brain plasticity and mental health in aging.

Optical Properties of GaSb Nanofibers

Nanoscale Research Letters, 2011
Amorphous GaSb nanofibers were obtained by ion beam irradiation of bulk GaSb single-crystal wafers, resulting in fibers with diameters of ~20 nm. The Raman spectra and photoluminescence (PL) of the ion irradiation-induced nanofibers before and after ...
