Proposal of a FET-LET Hybrid 6T SRAM
Antardipan Pal, Yong Zhang, Dennis D. Yau
There is an extremely high demand for a high speed, low power, low leakage, and low noise Static Random-Access Memory (SRAM) for high performance cache memories. The energy efficie…
Comparative studies of optoelectrical properties of prominent PV materials: Halide Perovskite, CdTe, and GaAs
Fan Zhang, Jose F. Castaneda, Shangshang Chen +13
We compare three representative high performance PV materials: halide perovskite MAPbI3, CdTe, and GaAs, in terms of photoluminescence (PL) efficiency, PL lineshape, carrier diffus…
Growth of Thin Oxidation-Resistive Crystalline Si Nanostructures on Graphene
Naili Yue, Joshua Myers, Liqin Su +5
We report the growth of Si nanostructures, either as thin films or nanoparticles, on graphene substrates. The Si nanostructures are shown to be single crystalline, air stable and o…
Microscopic structure differences in CZTSe quaternary alloys prepared by different techniques revealed by spatially-resolved laser-induced-modification Raman spectroscopy
Qiong Chen, Sergio Bernardi, Yong Zhang
While producing comparable efficiencies and showing similar properties when probed by conventional techniques, such as Raman, photoluminescence and X-ray diffraction, two thin film…
Raman study of lattice vibrations in type II superlattice InAs/InAs1-xSbx
Henan Liu, Yong Zhang, Elizabeth H. Steenbergen +10
In this work, we report a polarized Raman study on the vibrational properties of the InAs/InAs1-xSbx SLs as well as selected InAs1-xSbx alloys, all grown on GaSb substrates by eith…
In-Situ Monitoring of Thermal Annealing Induced Evolution in Film Morphology and Film-Substrate Bonding in a Monolayer MoS2 Film
Liqin Su, Yifei Yu, Linyou Cao +1
We perform in-situ two-cycle thermal cycling and annealing studies for a transferred CVD-grown monolayer MoS2 on a SiO2/Si substrate, using spatially resolved micro-Raman and PL sp…
Multiple-stage structure transformation of organic-inorganic hybrid perovskite CH3NH3PbI3
Qiong Chen, Henan Liu, Hui-Seon Kim +8
By performing spatially resolved Raman and photoluminescence spectroscopy with varying excitation wavelength, density, and data acquisition parameters, we have achieved a unified u…
Light-effect transistor (LET) with multiple independent gating controls for optical logic gates and optical amplification
Jason K. Marmon, Satish C. Rai, Kai Wang +2
Modern electronics are developing electronic-optical integrated circuits, while their electronic backbone, e.g. field-effect transistors (FETs), remains the same. However, further…
Efficient Interlayer Relaxation and Transition of Excitons in Epitaxial and Non-epitaxial MoS2/WS2 Heterostructures
Yifei Yu, Shi Hu, Liqin Su +8
Semiconductor heterostructures provide a powerful platform for the engineering of excitons. Here we report the excitonic properties of two-dimensional (2D) heterostructures that co…
