We report a new experimental setup enabling local electrochemical impedance spectroscopy (LEIS) measurements over wide frequency range, including the low domain. First, an improved signal treatment was performed using potential shifter to minimize DC component of measured potential, allowing for AC be probed ideal system. Then, unique, three-electrode LEIS probe implemented study influence radi...

Flip chip joining technology using anisotropically conductive films (ACFs) has become an attractive technique for electronic packaging. However, several factors have hindered the wide spread use of this technology. Along with the reliability issue, these factors also include the low availability and high cost of the bumped wafers. This paper introduces the feasibilities of using unbumped die wi...

Abstract Understanding the energy alignment of electronic bands, which originate from ultrathin MoS 2 layers and metal electrodes attached to them, is crucial for design -based devices. We have applied internal photoemission spectroscopy (IPE) analyze this alignment. demonstrate that IPE can yield barrier heights in metal/ two-dimensional semiconductor/insulator stacks when top electrode suffic...

Aluminum–sulfur batteries employing high-capacity and low-cost electrode materials, as well non-flammable electrolytes, are promising energy storage devices. However, the fast capacity fading due to shuttle effect of polysulfides limits their further application. Herein, alkaline chlorides, for example, LiCl, NaCl, KCl proposed electrolyte additives promoting cyclability aluminum–sulfur batteri...
