JoVE Engineering
JoVE Engineering encompasses a broad range of experimental and instrumental techniques utilized in physics research. Investigations in this area strive to address and answer a broad range of scientific questions, such as device mechanisms and efficiencies, using physical tools. This approach often requires a combination of specialties, and research in this area tends to be interdisciplinary with contributions from mechanical, electrical, and chemical engineers.

A Method for Studying the Temperature Dependence of Dynamic Fracture and Fragmentation

1Institute of Shock Physics, Imperial College London


JoVE 52463

Fracture and fragmentation are late stage phenomena in dynamic loading scenarios and are typically studied using explosives. We present a technique for driving expansion using a gas gun which uniquely enables control of both loading rate and sample temperature.

In Situ Time-dependent Dielectric Breakdown in the Transmission Electron Microscope: A Possibility to Understand the Failure Mechanism in Microelectronic Devices

1Fraunhofer Institute for Ceramic Technologies and Systems, 2Dresden Center for Nanoanalysis, Technische Universität Dresden, 3Globalfoundries Fab 8, 4Globalfoundries Fab 1


JoVE 52447

The time-dependent dielectric breakdown (TDDB) in on-chip interconnect stacks is one of the most critical failure mechanisms for microelectronic devices. This paper demonstrates the procedure of an in situ TDDB experiment in the transmission electron microscope, which opens a possibility to study the failure mechanism in microelectronic products.

Formation of Thick Dense Yttrium Iron Garnet Films Using Aerosol Deposition

1Power Electronics Branch, Naval Research Laboratory, 2Physics of Electronic Materials Branch, Naval Research Laboratory


JoVE 52843

This report describes the use of a custom-built system to perform aerosol deposition of thick films of yttrium iron garnet onto sapphire substrates at RT. The deposited films are characterized using scanning electron microscopy, profilometry, and ferromagnetic resonance to give a representative overview of the capabilities of the technique.

Visualization of High Speed Liquid Jet Impaction on a Moving Surface

1Department of Mechanical Engineering, University of British Columbia


JoVE 52603

Two experimental devices for examining liquid jet impingement on a high-speed moving surface are described: an air cannon device and a spinning disk device. The apparatuses are used to determine optimal approaches to the application of liquid friction modifier (LFM) onto rail tracks for top-of-rail friction control.
