— In this letter, we introduced hydrogen ions into titanium metal doped into SiO 2 thin film as the insulator of resistive random access memory (RRAM) by supercritical carbon dioxide (SCCO) 2 fluid treatment. After treatment, low resistance state split in to two states, we find the insert RRAM, which means it has an operating polarity opposite from normal(More)
We have searched three hot molecular cores for submillimeter emission from the nucleic acid building-block pyrimidine. We obtain upper limits to the total pyrimidine (beam-averaged) column densities towards Sgr B2(N), Orion KL and W51 e1/e2 of 1.7 × 10 14 cm −2 , 2.4 × 10 14 cm −2 and 3.4 × 10 14 cm −2 , respectively. The associated upper limits to the(More)
To improve the operation current lowing of the Zr:SiO2 RRAM devices, a space electric field concentrated effect established by the porous SiO2 buffer layer was investigated and found in this study. The resistive switching properties of the low-resistance state (LRS) and high-resistance state (HRS) in resistive random access memory (RRAM) devices for the(More)
Arcsecond-resolution spectral observations toward the protobinary system IRAS 16293-2422 at 344 and 354 GHz were conducted using the Submillime-ter Array. Complex organic molecules such as CH 3 OH and HCOOCH 3 were detected. Together with the rich organic inventory revealed, it clearly indicates the existence of two, rather than one, compact hot molecular(More)
Keywords: Nonvolatile resistance switching memory RRAM Yb 2 O 3 Forming This paper studies the effects of both the positive and negative forming processes on the resistive switching characteristics of a Pt/Yb 2 O 3 /TiN RRAM device. The polarity of the forming process can determine the transition mechanism, either bipolar or unipolar. Bipolar behavior(More)
Using the recently-commissioned Submillimeter Array (SMA), we have detected several complex organic molecules, including (CH3)2O, C2H5OH, C2H5CN, and tentatively CH2CDCN, toward the protostellar hot cores of IRAS 16293-2422 at arcsecond-resolution (400 AU in radius). Vibrationally excited transitions of SO, SO2 and HCN with energy levels up to 1800 K were(More)
