Would you please correct it These values are higher than those obtained by graphene-MoS2 phototransistor, lithographic-patterned GNR and few-layer-based photodetectors such as MoS2. The resistance of channels was increased with increasing the GNR stacks’ surface area. .........., combining optical lithography with written electrodes using electron-beam. Thanks

Would you please correct it It includes the device images, the transfer characteristics of three GNR stack devices probed in ambient, and also the SR measurements by applying bias corresponding to the negative values of their neutral points (NPs) due to decreasing the resistance at NPs.

English edition of paper Hello every body I am looking forward to a person who can help me in English edition of my paper. Who knows physics or electrical engineering. Thanks

General english speaking Dear all Do you have any suggestion for improving general English speaking? I know I have problem in English structure I used to speak with simple words! It is critical for my job I think not only fluent speaking is important but also well-structured sentences (developed one) is critical simple words are boring to listener Also, i think it is in general speaking category which is more applicable than TOEFl and IELTS in daily speaking.

He said that I just can acknowledge the use of the facility. Now I am writing the acknowledgement part of paper but I am not sure is the below sentences true for this situation or not. Firs author is gratefully appreciated of Professor .... for his support of the device fabrication and measurement presented here at (group name) group of (uni name) University.

Appology accepted I sent two email to my boss about my mistake. One of in one of them I said I am sorry as a short sentences (he didn't replied) in the other one I described the situation with an extended sentences of apology (He replied) Honestly, I had right to be worry but the way of my explanations was rude. He replied that "apology accepted, don't worry" But i have very bad feeling about it. I think it is not humble answer :( What do you think?

IBT toefl Hello every body, I am familiar with IBT toefl test. But I am confused to start study for it now. Do you have any suggestion to study toefl exam step by step?

What is your idea about TPO's of IBT exam? are they similar to IBT exam?

would you please correct it? (part 1) Since I remember, my passion in life has been to create new things. Consequently, My my creativity and my efforts was seen by Khwarazmi Award of Iran and They encouraged me three consecutive times. My interest in the technical aspects of Physics phenomena led me to pursue Solid state Physics at the .... University . Due to interest to have more scientific activities. I tried to establish Physics Society of there with my friends and two faculty of science of .... University . In addition, along with working on my M.Sc thesis, I cooperate to establish our new Laboratory in ....... University. After graduating, I wrote a booklet of Quantum mechanic Solution for Alpha Institute and I worked at high school as a teacher near 3 semesters. Now, I am junior PhD student of Solid State Physics of ........University . In choosing a subject for my final project (thesis), I was eager to work on the most challenge topic in carbon electronic. My project is."........."
