806. Hot electron emission processes in waveguide integrated graphene

Rehan Kapadia (University of Southern California)

1.1 Basic Phenomena;

Oral

Photoemission plays a central role in a wide range of areas, from electronic structure measurements to free electron laser sources. In metallic emitters, photons with energy lower than the material workfunction can only drive photoemission through the multi-photon, or strong-field processes, both of which require large optical power densities, limiting the integration and deployment of these...

653. Electron Emission and Gas Breakdown: Unification of Theory from Schrodinger’s Equation to Paschen’s Law

Amanda Loveless (Purdue University)

1.1 Basic Phenomena;

Oral

The continued miniaturization of electronic devices for applications including micro- and nano-electromechanical systems (MEMS and NEMS, respectively) and microplasmas requires a thorough understanding of electron emission behavior at these length scales for various pressures. Paschen’s law (PL) governs classical gas breakdown, but fails for microscale gaps, where field emission (FE) drives...

961. Microscale Gas breakdown voltage dependence on electrode surface

Russell Brayfield (Purdue University)

1.1 Basic Phenomena;

Oral

Surface structure, such as surface roughness and electrode geometry, can modify field enhancement and work function, which subsequently modifies field emission. This can significantly change gas breakdown voltage for microscale gaps at atmospheric pressure [1], where field emission drives breakdown rather than Paschen’s law. This presentation uses a tungsten pin anode and a copper plate...

1014. Quantum effects in electron emission from nanodiamond

Prof. Sergey Baryshev (Department of Electrical and Computer Engineering, Michigan State University)

25/06/2019, 10:45

1.1 Basic Phenomena;

Oral

Synthetic granular ultra-nano-crystalline diamond with high n-type conductivity via nitrogen doping ((N)UNCD) has emerged as a high efficiency photo- or field-emission source in that it has high internal and external quantum efficiency in near UV/visible or low turn-on field, respectively. It is widely anticipated that graphitic grain boundaries (surrounding diamond grains) are behind the high...

1213. Particle Emission Investigation from an Anode Liquid Surface of Electrolyte in Atmospheric Pressure DC Glow

Yao Kovach (University of Michigan)

25/06/2019, 11:00

1.1 Basic Phenomena;

Oral

Self-organization patterns observed on anode liquid surfaces in atmospheric pressure DC glow discharge represents both a mysterious and beautiful plasma physics phenomenon. The mechanisms underlying self-organization of plasmas in this context is still poorly understood. In this study, luminous particle emission from the liquid anode under self-organization condition has been observed. These...

659. ENGINEERED TUNNELING ELECTRICAL CONTACTS

Sneha Banerjee (Michigan State University)

25/06/2019, 11:15

1.1 Basic Phenomena;

Oral

Contact resistance and current transport are important to nano scale electrical contacts, such as those based on metal-insulator-metal (MIM) thin junctions, carbon nanotube (CNT) networks, and novel two-dimensional (2D) materials. Current tunneling and contact resistance across such contacts greatly influence the device properties and performance. Current crowding effects in these contacts can...

802. Theoretical investigation of the magnetic asymmetry effect by using a lumped element model

Mr Dennis Engel (Ruhr University Bochum)

25/06/2019, 11:30

1.1 Basic Phenomena;

Oral

Latest experimental results have proven the existence of the magnetic asymmetry effect (MAE) in radio frequency capacitively coupled magnetron discharges [1]. Like the electrical asymmetry effect, the MAE allows to control the symmetry of a capacitive discharge. This contribution presents a lumped element model for such an RF driven magnetron which is an extension of a previously published...
