Summary

Mediaarticle

Thepaper outlines how researchers used phase-shifting interferometry toascertain the number of phosphorene, that is, sticky tape to developsingle-atom-thick layers. By performing power-dependentphotoluminescence measurements, they were able to establish differentexcitonic features of a monolayer on a silicon substrate. Phosphoreneis a semiconductor and can be utilized in the current electronicstechnology. The paper also affirms that this property has never beenfound in another material.

Researchpaper

Themonolayer phosphorene avails a distinctive two-dimensional (2D)avenue to experiment the core dynamics of excitons and trions inlimited dimensions. Due to its propensity for being unstable, it hasnever been developed. In addition to that, features such as dynamicsof excitons have never been explored. However, this experiment showsa noninvasive, rapid, and highly accurate design to determine thephosphorene numbers. The results obtained in this experiment wouldopen many opportunities for exploration. The mechanisms used toconduct the test are quite accurate providing a platform for futureinnovations. The exciton binding was found to be ~0.3eV for monolayerphosphorene on SiO2. The results conformed to the theoreticalexpectations. A large trion binding energy of approximately 100meVwas seen in Si substrate of monolayer phosphorene.

Formatof the article

Mediaarticle

Thepaper is not formatted in a particular manner. Information is onlyprovided one paragraph after another. It has no abstract,introduction, body with subheadings and a conclusion. The points arejust explained in paragraphs.

Scholarlyarticle

Thereis a clear order from the beginning to the end of the article. Itstarts with the title and the people involved in the research. Anabstract explaining some of the concept utilized follows as well asmentioning of the keywords. An introduction and subsequentsubheadings are used to give a direction to the paper. A reader canquickly follow-up the details and if applicable try the experiment byhis own. It outlines the materials and the methods used to ascertainthe test. By discussing the results, a reader can be enlightened onwhat to expect. A list of a figure and respective explanations areavailed for the user to go through. The article gives some thereferences necessary in case one would want to refer.

Thescholarly article is well-formatted and readable. A person gettingthe information from the research article would understand theexperiment quite easily that the one reading the media one.

Experimentalresults in the press article

Thearticle just gives an outline of what the project does. It does notprovide an in-depth analysis of the experiment. The generalinformation entails what the research is supposed to attain and howit is of benefit. However, there are no tables or charts to representthe pictorial view of the experiment. It seems to dwell much on thepeople involved in the research without necessarily discussing howthe results were achieved. A reader may not get the full informationregarding the project if he/she does not get the actual document.Media information only tends to arouse interest. An interested partywould just go through the media article and look for the scholarlyone to get enough information.

Comparingthe conclusions

Thetwo ends tend to defer. Though the press report does not incorporatea conclusion subheading, it mentions the need to refer to thescholarly article for further information. The paper from the mediadoes not summarize outcomes obtained from the experiment. On theother hand, the academic article gives a summarized discussion aboutthe findings. The research paper’s conclusion generalizes resultsproviding explanation how it came. It further offers insights of howthe development could boost future innovations. The research paperconcludes the entire outcomes. For instance, the results obtained inthis experiment would open many opportunities for exploration. Themechanisms used to conduct the analysis are entirely accurateproviding a platform for future innovations. The exciton binding wasfound to be ~0.3eV for monolayer phosphorene on SiO2. The resultsconformed to the theoretical expectations. A large trion bindingenergy of approximately 100meV was seen in Si substrate of monolayerphosphorene. By going through the conclusion part, one can understandwhatever is entailed in the entire document.

Criticizingdata

Botharticles tend to conform to the fact that this experiment isaccurate. In fact, as noted by the scholarly paper, “this approachto establish layer number of mono-and few-layer phosphorene utilizingPSI, is noninvasive, rapid, and highly accurate.” The media articledoes not offer any criticism. It only directs a reader towardsassessing the scholarly document.

Themedia article fails to mention the mathematical concepts involved. Onviewing the academic material, one can realize the mathematicalformulas involved are quite complicated. A reader must beacclimatized to some of these concepts to understand precisely howthe experiment is achieved. It may seem easier when viewing the mediaarticle since it does not incorporate the complex mathematicsinvolved to arrive at the results. The media paper does not providean alternative concept hence it dwells more on the theoreticalaspects. Nevertheless, the scholarly paper uses the concepts to itsappropriateness. Maybe provision of other ideas that negate usage ofmathematical formulas would be helpful.

Thetitle given to the article does not clearly outline what theexperiment involves. It partially lets the reader know what theexperiment is all about, but one cannot understand the full contextunless he/she reads the whole passage. Titles given to articles bymedia are meant to entice the reader. They are crafted in aparticular manner to look appealing to the reader. Sometimes onecannot understand what the passage is all about until he/she looksdeeper. The same case applies to this article. “Sticky tape andphosphorus the key to ultrathin solar cells” is the media’sheading. Compared to the research paper title “Optical Tuning ofExciton and Trion Emissions in Monolayer Phosphorene”, the do notconform to each other. Actually, someone may think the two titles arereferring to two different things. There is no clear relation betweenthe two titles.

Theexercise has been quite helpful. Unlike scholarly articles, mediapapers are shallow regarding content. They are only meant to give thepartial reader information, and an interested person can researchfurther. Scientific research is detailed, and many facts have to bebrought together to achieve precise results. The concepts rely onother subjects such as mathematics to ensure clarity. A scienceresearcher has to be knowledgeable in various fields to come up witha satisfactory document. Media covers are not that detailed hencerequire fewer skills as compared to science researcher.
