Synthesis of Metal-Semiconductor Heterojunctions in Single Graphene Nanoribbons

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Michael Crommie | Summary:Graphene nanoribbons (GNRs) are a highly tunable class of one-dimensional (1D) quantum materials that can be fabricated through bottom-up synthesis. Precise control over GNR band gaps and band-edge alignments has established them as a promising nanoelectronics platform, but forming high-quality electronic interfaces remains challenging. Here we combine sequential on-surface synthesis […]

Independent Amplitude and Phase Modulation in Active Transmissive Metasurfaces via Complex Permittivity Tuning

Posted by klaurent Caltech, This Week: Nanoscience

Kavli Affiliate: Harry Atwater | Summary:Active metasurfaces are a promising platform for spatial light modulators (SLMs) in applications such as holography, beam shaping, and light detection and ranging (LiDAR), as they enable dynamic control over the amplitude and phase of light at subwavelength scales. Among these, transmissive metasurfaces offer a compact alternative to conventional SLMs, […]

Parallax Depth Sectioning and 3D Reconstruction in 4D-STEM

Posted by klaurent Cornell, This Week: Nanoscience

Kavli Affiliate: David Muller | Summary:Three-dimensional (3D) information is encoded in four-dimensional scanning transmission electron microscopy (4D-STEM) through parallax between the virtual images formed at each detector pixel. In this paper we connect the encoding and retrieval of depth-dependent information in 4D-STEM to two other widely-used 3D imaging methods, tomography and light-field photography, and derive […]
