2024年3月13日,中国科学院长春光机所佟存柱研究员团队在光子晶体面发射激光器(PCSEL)研究领域取得重要进展,提出三晶格结构并实现低阈值1550nm PCSEL,相关成果发表在Light:Science and Application vol.13,44,2024,国际半导体行业著名刊物《Semiconductor Today》以“Triple-lattice photonic ...
With a little twist and the turn of a voltage knob, Cornell researchers have shown that a single material system can toggle between two of the wildest states in condensed matter physics: the quantum a...
华中科技大学武汉光电国家研究中心陈长清、戴江南研究团队近11年以来一直从事半导体深紫外发光芯片和器件领域(重点围绕Deep Ultraviolet Light Emitting Diodes和Deep Ultraviolet Laser Diodes)的研究工作。近日,国际半导体业界权威刊物《Semiconductor Today》和《Compound Semiconductors》相继报道团队研...
The authors consider the problem of wafer temperature control in rapid thermal processing (RTP) of semiconductor wafers. They present a novel approach to the analysis of candidate sensor configuration...
JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We concentrate on ultimate-fast optical switching of the cav...
Abstract: We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We ...
We present a novel 2D position-sensitive semiconductor detector manufactured using the conventional planar technology used in the production of single-side AC-coupled microstrips sensors. In the new d...
A novel and simple model is proposed for the measurement of the linewidth enhancement factor (LEF) α of multiwavelengths semiconductor laser. It is based on the suppression characteristics of an arbit...
Optical response of an artificial composite nano-dimer comprising a semiconductor quantum dot and a metal nanosphere is analyzed theoretically. We show that internal degrees of freedom of the system c...
Physicists in the US and the UK have found a way to store and read data in nuclear spins using electronic pulses. The breakthrough could help in the development of spintronic systems that process info...
In this paper we are using formal analogy of electromagnetic wave equation and Schr¨odinger equatio in order to study the phenomenon of perfect tunneling (tunneling with unitary transmittance)in 1D se...
Optical cavity cooling of mechanical resonators has recently become a research frontier [1–3]. The cooling has been realized with a metal-coated silicon microlever via photo-thermal force [4] and subs...
The quantum Boltzmann equation, or Fokker-Planck equation, has been used to successfully explain a number of experiments in semiconductor optics in the past two decades. This paper reviews some of the...
We present transport measurements of a tunable silicon metal-oxide-semiconductor double quantum dot device with lateral geometry. Experimentally extracted gate-to-dot capacitances show that the device...
