Optically Controlled Supercapacitors with Semiconductor Embedded Active Carbon Electrodes
H. Grebel
Supercapacitors, S-C - capacitors that take advantage of the large capacitance at the interface between an electrode and an electrolyte - have found many short-term energy applicat…
Asymmetric supercapacitors: optical and thermal effects when active carbon electrodes are embedded with nano-scale semiconductor dots
H. Grebel
Optical and thermal effects in asymmetric supercapacitors, whose active-carbon (AC) electrodes were embedded with nano-Si (n-Si) quantum dots (QD), are reported. We describe two st…
Parametric Oscillation and amplification with gate controlled capacitor-within-capacitor
H. Grebel
A Capacitor-within-Capacitor (CWC) is a nested electronic element that has two components: the cell (e.g., the outer capacitor) and the gate (e.g., the inner capacitor). The design…
Ion-liquid based super-capacitors with inner gate diode-like separators
Tazima S. Chowdhury, Haim Grebel
We demonstrate that the capacitance of ionic-liquid filled supercapacitors is substantially increased by placing a diode-like structure on the separator membrane. We call the struc…
Optical Cages
V. Kumar, J. P. Walker, H. Grebel
We examine array of metal-mesh frameworks for their wide-band absorption. These take the form of quasi-crystal optical cages. An array of cages tends to focus the incoming radiatio…
Life-time and line-width of individual quantum dots interfaced with graphene
Xin Miao, David J. Gosztola, Anirudha V. Sumant +1
We report on the luminescence's life-time and line-width from an array of individual quantum dots; these were interfaced with graphene surface guides or dispersed on a metal film.…
