We report a high detectivity of 3×1011 cm Hz1/2/W at 78 K for normal-incidence quantum dot infrared photodetectors with ten layers undoped InAs/InGaAs/GaAs active regions. The seen 1.4 V corresponds to photoresponse peaks 9.3 and 8.7 μm positive negative bias, respectively.
Because of the increasing difficulty in obtaining natural aggregate, alternative aggregates have been considered construction industry. One feasible alternatives is to reuse and demolition waste as aggregates, called recycled make new concrete aggregate (RAC). However, compressive strength RAC usually poor due primarily high water absorption capacity, porosity, weaker bond interfacial transition zone between cement mortar. This paper presents results a comprehensive experimental study on...
Nowadays, for lanthanide fluorescence thermometry, high relative temperature sensitivity (Sr) and wide sensing range are urgently required in practical applications. Herein, a Pr3+-doped scandate (Pr3+:CaSc2O4) luminescent thermometer is proposed, the related crystal-field splitting of Pr3+ ions systematically discussed. The 4f5d-4f 4f-4f emissions CaSc2O4 basically present positive negative correlation relationships with increase temperature, respectively. different changing tendencies...
Due to their remarkable mechanical properties, graphene nanoplatelets (GNPs) are widely employed reinforce matrix components such as cement materials. Recent findings have indicated that GNPs can be used additives improve the properties of cement. However, enhancement mechanism is still indefinite. In order investigate reinforcement mechanism, this work studied effect on hydration behaviour Portland through an experimental investigation with isothermal calorimetry and thermogravimetric...
We report InAs quantum dot infrared photodetectors that utilize In0.15Ga0.85As strain-relief cap layers. These devices exhibited normal-incidence photoresponse peaks at 8.3 or 8.8 μm for negative positive bias, respectively. At 77 K and −0.2 V bias the responsivity was 22 mA/W peak detectivity D* 3.2×109 cm Hz1/2/W.
We report noise characteristics, carrier capture probability, and photoconductive gain of InAs quantum-dot infrared photodetectors with unintentionally doped active regions. At 77 K, a 750 was observed at bias 0.7 V. The high is result the low probability: p=0.0012.
A sulfoaluminate cement was, for the first time, used to fabricate 0-3 piezoelectric composites by a compressing technique. The dependences of properties on content PZT and poling conditions are discussed. results show that improved increasing field E time t, but when t exceeded 4.0 kV mm−1 45 min, d33 tends be constant. constants electromechanical coupling coefficients Kp, Kt increase rapidly with PZT. When reaches 85%, Kp 28.54% 28.19%, respectively.
