Defining the plasmonic cavity performance based on mode transitions to realize highly efficient device design

“…The cube was modeled as having rounded corners, with a radius of curvature of 8 nm, as described previously. 11,41 The disk thickness was fixed to 30 nm. The near-field enhancement numbers for a disk with t = 2 nm and a cube were comparable.…”

“…In recent years, plasmonics has attracted potential interest for use in highly efficient devices in the fields of energy conversion, fuel generation, sensors, and photonic devices. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Understanding plasmonic mode fundamentals and properties is critical, as these factors play a defining role in material performance. [15][16][17][18][19][20][21] Factors like flexibility and simplicity in fabrication, good geometrical tolerance, large dielectric layer thicknesses with superior device characteristics, and low-cost processing are essential for developing next-generation devices with multiple applications.…”

“…These properties are fundamental to realizing highly efficient devices in the fields of energy conversion, chemical/biological sensors, cavity quantum electrodynamics, surface-enhanced spectroscopies, single molecule detection, and waveguiding. 4,7,9,11,19,27,[35][36][37][38][39][40][41][42][43] The importance of the above-mentioned plasmonic modes is illustrated by plasmonic nanoparticle-film coupled systems, commonly referred to as nanoparticle (NP) on mirror or NPOM systems. These systems display rich plasmonic modes and have a high potential technological utility.…”

“…These systems display rich plasmonic modes and have a high potential technological utility. 11,16,19,27,35,41,44,45 These NPOM designs mimic theoretical free-space dimer (FSD) designs, in which two metallic nanoparticles (NPs) are separated by a nanogap distance to create a hot spot. 36,44,45 The dielectric layer inserted between the NP and mirror acts as a virtual hot-spot region, in which attractive plasmonic properties can be realized.…”

Assembling Nano–Microarchitecture for Electromagnetic Absorbers and Smart Devices

“…They enable connecting the world together, with unexpected surprising convenience ( Figure ). [ 1–35 ] In recent years, 3D nano–micro architectures are emerging. At the same time, new technologies, new effects, new mechanisms, new materials, and new structures are bringing limitless vitalities to smart devices, and driving them towards integration, diversification, miniaturization, high performance, precision, and so on.…”
