AI Thread Summary
Graphene research has seen a surge in interest over the past decade, leading to a competitive landscape for PhD candidates. The influx of researchers raises concerns about the ability to make significant contributions in a crowded field, as established competitors may dominate impactful research. The job market for PhD graduates in this area could become saturated, especially if funding decreases as the initial excitement wanes. Transitioning to other areas within nanoscience, such as microfluidics or microrobotics, may be feasible after specializing in graphene, particularly if the focus is on broader concepts like thin films rather than solely on graphene itself. Emphasizing expertise in thin films could provide more versatile career opportunities in various industries.

Graphene research has been going on for a decade now, with huge numbers of researchers piling into get a cut of the magic. I have a PhD offer in the topic of the mechanical properties of graphene, and I am pondering whether to accept and join the bandwagon myself.

I would be interested to hear people's experiences and opinions on situations like this, in which there is a sudden explosion in research in a completely new area. I have a few questions of my own:


1. Does the fact that so many people are in the field now mean that it will be harder to do a phd with a strong impact? With so many competitors who have been in the field a while, is it not harder for a student to catch up and do something worthwhile in their thesis when the pace of the field is so great?

2. What happens to the job market in these situations? Will the large cohort of phd students trained in the graphene boom years be in trouble when research subsides and funding decreases?

3. After my graphene phd, how easy would it be to move to a different area of research in the broader field of nanoscience/nanotech? If I had been trained in 2D materials, could I make the move to say microfluidics or microrobotics or similar?


I have little understanding or insight into the pro's and con's of joining emerging fields such as this, so would be grateful for any offered here. Cheers!

I am wondering the same thing because I am considering joining a graphene research group when I start grad school this Fall.
 
The advantage of a hot field is that it is interesting and there are a lot of people working on it. The disadvantage of a hot field is that it is interesting and there are a lot of people working on it.

I think it is a mistake to think of this as a process that makes you a graphene expert. It would be much wiser to think of this as a process that makes you an expert in thin films and particularly mechanical properties of thin films.
 
^^very excellent observation considering that thin films are actually a very broad and important topic with lots of flexible avenues of study and potential in industry.
 
Be an investor rather than an investigator...
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
