Passive temperature management based on near-field heat transfer
Sen Zhang, Wei Du, Wenjie Chen +3
Thermal or temperature management in modern machines has drawn great attentions in the last decades. The waste heat caused during the machine operation is particularly pernicious f…
High-speed and high-responsivity hybrid silicon/black-phosphorus waveguide photodetectors at 2 μm
Yanlong Yin, Rui Cao, Jingshu Guo +13
Silicon photonics is being extended from the near-infrared (near-IR) window of 1.3-1.5 μm for optical fiber communications to the mid-infrared (mid-IR) wavelength-band of 2 μm or l…
Daytime passive radiative cooler using porous alumina
Yang Fu, Jiang Yang, Yishu Su +2
We report a daytime passive radiative cooler using chemically fabricated porous anodic aluminum oxide (AAO) membranes. Effective medium theory (EMT) has been applied to analyzing t…
Observing of the super-Planckian near-field thermal radiation between graphene sheets
Jiang Yang, Yishu Su, Yang Fu +4
Thermal radiation can be substantially enhanced in the near-field scenario due to the tunneling of evanescent waves. The monolayer graphene could play a vital role in this process…
