Effects of 450 MeV Kr Swift Heavy Ion Irradiation on GaN-Based Terahertz Schottky Barrier Diodes [PDF]

Micromachines
GaN-based terahertz (THz) Schottky barrier diodes (SBDs) are critical components for achieving high-power performance in THz frequency multipliers. However, the space applications of GaN-based THz SBDs are significantly constrained due to insufficient ...

Robust water repellent ZnO nanorod array by Swift Heavy Ion Irradiation: Effect of Electronic Excitation Induced Local Chemical State Modification [PDF]

Scientific Reports, 2017
Tailoring the surface properties by varying the chemistry and roughness could be of interest for self-cleaning applications. We demonstrate the transformation of hydrophobic ZnO Nano rod (NR) array into superhydrophobic nature by changing the local ...

Study of Swift Heavy Ion Modified Conducting Polymer Composites for Application as Gas Sensor [PDF]

Sensors, 2006
A polyaniline-based conducting composite was prepared by oxidativepolymerisation of aniline in a polyvinylchloride (PVC) matrix. The coherent free standingthin films of the composite were prepared by a solution casting method.

Substrate-dependent pore formation in molybdenum disulfide monolayers under ion irradiation [PDF]

Beilstein Journal of Nanotechnology
Ion irradiation is a versatile tool for nanostructuring surfaces, yet the roles of energy deposition and dissipation at the surface and in ultrathin materials remain poorly understood. In this study, we investigate nanopore formation in monolayer MoS2 on

Swift heavy ion tracks in nanocrystalline Y4Al2O9

Nuclear Materials and Energy, 2022
We report the first results of a TEM study of structural changes induced by high energy xenon and bismuth ions in Y4Al2O9 nanoparticles (10 to 100 nm grain size) in the range of electronic stopping powers 6 ÷ 35 keV/nm.

Review of Swift Heavy Ion Irradiation Effects in CeO₂

Quantum Beam Science, 2021
Cerium dioxide (CeO2) exhibits complex behavior when irradiated with swift heavy ions. Modifications to this material originate from the production of atomic-scale defects, which accumulate and induce changes to the microstructure, chemistry, and ...

ELECTRON KINETICS OF YTTRIUM IRON GARNET AFTER SWIFT HEAVY ION IMPACT

Eurasian Physical Technical Journal, 2022
The TREKIS Monte-Carlo model was applied to study the temporal electronic kinetics of yttrium iron garnet after a swift heavy ion impact. Cross sections of incident particles interaction with the target were determined within complex dielectric ...

Ionoacoustic detection of swift heavy ions [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2020
The maximum energy loss (Bragg peak) located near the end of range is a characteristic feature of ion stopping in matter, which generates an acoustic pulse, if ions are deposited into a medium in adequately short bunches. This so-called ionoacoustic effect has been studied for decades, mainly for astrophysical applications, and it has recently found ...
