Supplemental Material: Creating and Steering Highly Directional Electron Beams in Graphene

چکیده
on the electron beam generated by the lensing apparatus described in the main text. All numerical examples are meant to be compared with (and are being based on the same parameters as) the ideal case of Fig. 1(c) in the main text, which considers a focal length f = 200nm, densities no = −ni = 6× 1011 cm−2 corresponding to a Fermi wave length λF ≈ 46nm, and a smoothness `s = 30nm of the pn junction profile. Moreover, we comment on the expected temperature dependence in the closing.

Creating and Steering Highly Directional Electron Beams in Graphene.
We put forward a concept to create highly collimated, nondispersive electron beams in pseudorelativistic Dirac materials such as graphene or topological insulator surfaces. Combining negative refraction and Klein collimation at a parabolic pn junction, the proposed lens generates beams, as narrow as the focal length, that stay focused over scales of several microns and can be steered by a magne...
متن کاملCreating and Manipulating Electron Beams in Graphene
An electron collimator composed of a point-like source and a parabolic pn junction is proposed as a generator of highly focused electron beams in graphene. The collimator is based on negative refraction and Klein collimation, which are unique to pseudo-relativistic Dirac materials. The electron beams generated by the lensing apparatus can be steered by a weak magnetic field without losing colli...
متن کاملAbsorptive pinhole collimators for ballistic Dirac fermions in graphene
Ballistic electrons in solids can have mean free paths far larger than the smallest features patterned by lithography. This has allowed development and study of solid-state electron-optical devices such as beam splitters and quantum point contacts, which have informed our understanding of electron flow and interactions. Recently, high-mobility graphene has emerged as an ideal two-dimensional se...
متن کاملHighly directional multi-beam audio loudspeaker
This work presents an audio beam loudspeaker that possesses the capability of emitting multiple audio beams into different directions at the same time. Ultrasonic loudspeakers applying parametric array technology are used to generate highly directional audible sound beams. The loudspeaker itself appears as a single device and can be mounted under the ceiling of a room in order to supply selecte...
متن کاملMacroscopic graphene membranes and their extraordinary stiffness.
The properties of suspended graphene are currently attracting enormous interest, but the small size of available samples and the difficulties in making them severely restrict the number of experimental techniques that can be used to study the optical, mechanical, electronic, thermal, and other characteristics of this one-atom-thick material. Here, we describe a new and highly reliable approach ...
