Two types of indenters such as Berkovich and spherical indent radii of 5 and 10 µm were used in various indent loads on the surface of SE and SMA foils. Elastic and thermal surface recovery was estimated for the SE and SMA alloys at both indenters. SE sample shows the maximum recovery from deformation of 95 % at the load of 25–50 mN for the spherical indenter. However, SMA samples show a maximum recovery after heating on residual imprints of indent depth of 79 % at 250 mN load for spherical indenters. Elastic recovery in SE NiTi sample results from reverse phase transformation during unloading, however in SMA, this results from stress induced martensitic transformation. On thermal recovery SE shows recovery from shape memory region and martensite shows recovery from stress induced martensitic region. In multicycle tests, it was observed a first relative quick functional degradation of the material response, in terms of recovery capability, and a subsequent stabilization that typically occurs. Multicycle nanoindentation was performed for SE and SMA samples with a maximum load of 10 mN with a dwell time of 1s. SE shows elastic behaviour of the hysteresis curve that stabilizes after 10 cycles, however, SMA shows unrecovered strain with plasticity. On increment of the load up to 200 mN, the multicycle local indentation for SE represents the recovery of depth on each load, however overall, the unrecovered depth increases with load.

The structure and properties of oCVD films can be tuned by controlling the process parameters such as the flow rates of the vapor-phase reactants, substrate temperatures, chamber pressure, inert gas flow rate, and deposition time. Although the first three parameters have been studied, the impact of the last two remains as yet unexplored. This study examines how the flow rate of nitrogen gas, an inert gas that assists the oxidant delivered into the reactor chamber, and the deposition time affect the structure and properties of oCVD film. Polypyrrole (PPy) was chosen in this study due to its versatility for many applications. The results showed that nitrogen gas primarily acts as an oxidant carrier gas, impacting the distribution of the oxidant adsorbed onto the substrates. This leads to varying structure and properties of the resultant PPy. Furthermore, nitrogen flow rate and deposition time affect the thickness and conductivity of PPy differently. Increasing nitrogen flow rate significantly improves the distribution of the oxidant, but it can also result in excessive polaronic defects. These defects can severely deteriorate the polymeric structure and reduce the conductivity. Meanwhile, extending the deposition time increases the film thickness linearly due to longer reaction time and initially enhances conductivity until it reaches a plateau. These insights can be beneficial not only for the oCVD method but also for other types of vapor-based polymerization techniques.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100673"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the practical implementation of HPOs is limited by their stability and cost.

Recently, amorphous indium gallium zinc oxide (a-IGZO) has gained prominence for its application to stackable 3-dimensional (3D) dynamic random-access memory (DRAM) due to its ultra-low off-current and low-temperature fabrication. However, a high contact resistance of a-IGZO still limits the device performance. Despite various attempts to address the high contact resistance issue, including the metal-interlayer-semiconductor (MIS) contact structure, a novel approach is needed. Here, we propose an oxygen-scavenger-layer MIS (OSL MIS) contact structure which employs oxygen areal density (OAD) modulated OSL as the interlayer. The OSL MIS has been shown to improve the contact resistance through three key effects. 1) The interlayer doping effect, 2) a diffusion of oxygen ions from a-IGZO to interlayer, generates shallow donors in a-IGZO, and 3) the movement of oxygen ion induces the interface dipole. With these effects, the effective SBH and a contact resistivity were reduced to 0.119 eV and 1.36E-5 Ω·cm<sup>2,</sup> respectively. The proposed OSL MIS contact structure of a-IGZO using OAD modulation technique, shows enormous potential in improving the performance of amorphous oxide semiconductor based advanced electronic devices.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100676"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143183292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
