Subject: PhD inquiry — computational screening of perovskite passivation ligands

Dear Professor,

Your group's recent work on high-throughput screening of defect-passivating ligands for halide perovskites connects directly to my master's research, and I am writing to ask about PhD openings for 2027.

At Sharif University of Technology, my M.Sc. thesis in physical chemistry used DFT to screen 48 candidate ammonium-based passivators for surface iodide vacancies in FAPbI3. Three candidates showed binding energies and predicted trap-depth reductions strong enough that an experimental partner group synthesized films with our top pick, measuring a 60-nanosecond improvement in carrier lifetime. The joint paper is in preparation, with the computational half — mine — complete. What drew me to your group specifically is your descriptor-based approach to ligand generality across compositions; my screening produced early evidence for one of the electronic descriptors your recent paper proposes, from an independent dataset.

I would welcome the chance to discuss whether my background fits your group's plans. My CV and a two-page research summary are attached.

Best regards, Pouya Ebrahimi M.Sc. Chemistry, Sharif University of Technology

Dear Professor,

A brief follow-up on my note from last week about PhD positions for 2027. One update since then: our experimental collaborators have reproduced the carrier-lifetime improvement on a second batch of films, which firms up the screening result I described. If your group expects openings, I would be glad to send the full research summary or discuss at your convenience.

Best regards, Pouya Ebrahimi

Subject: Re: PhD inquiry — computational screening of perovskite passivation ligands

Dear Professor,

This is a final short note before I finalize my application list for 2027. Your group remains my first choice on research fit, and I will apply to the program either way. If supervision capacity is unlikely, a one-line reply would help me plan honestly — and if a colleague's group might be a better match for descriptor-based ligand screening, I would value the pointer.

Thank you for considering this.

Best regards, Pouya Ebrahimi
